An email from Delta’s mileage program recently announced that you could get 3 miles for every dollar spent at Home Depot. We’d been planning to buy a new grill there anyway, so I went through the SkyMiles Mall site to get to Home Depot, where I used a coupon from DealNews.com to get $100 off the purchase. We charged the grill and some accessories it to our Starwood Preferred Amex card, earning us 723 points in that program for future travel plus 1,977 frequent flier points in Delta’s program.

It’s not enough to get a free trip, of course, but the rewards do eventually add up. In recent months we’ve used various frequent traveler programs to:

• Get a free week at the Westin resort in Maui
• Book a bedroom on Amtrak for an overnight trip
• Get two free roundtrips to New York and one free roundtrip to Maui

Here’s how you can supercharge your travel rewards:

Use your rewards program’s shopping mall. For years I avoided these “malls,” thinking they were just online boutiques with overpriced merchandise. D’oh! In reality, the shopping malls operated by most frequent flier programs are simply portals that pass you through to the online merchants you already use. But by starting your shopping trip at the mall, you earn frequent flier rewards on the money you spend. You can use online coupons and other discounts just as if you’d started your trip at the retailer. The Mileage Mall at Webflyer.com keeps track of the offers at various frequent flyer online shopping malls and singles out the 20 best deals.

Spend money with program partners. You probably know you can earn frequent flier miles by renting cars or booking hotel nights with an airline program’s partner companies. But you also can get miles when you refinance your mortgage, sign up for cell service or eat a restaurant meal. It’s worth regularly reviewing the partner offers listed on your frequent traveler programs’ Web sites, and checking in with Webflyer’s Mileage Mall before you make a big purchase or open new accounts. Right now I’m kicking myself for not knowing that Mozy’s online backup service offered 3,000 Delta miles for new accounts, since I just opened one.

Sign up for your rewards programs’ email newsletters. You’ll be alerted to special deals you might miss otherwise. Virtually every program has limited-time offers that give you bonus miles or points. Right now, Continental offers double miles for La Quinta stays; Delta gives bonus miles for stays at Marriott and Hilton hotels, while American is offering up to 50,000 bonus miles for roundtrips between JFK and Los Angeles or San Francisco for first- and business-class trips, and 25,000 miles for coach tickets booked in Y, D or I categories.

Get elite status. Airline and hotel programs typically have multiple tiers of membership; the higher you go, the more rewards points you earn for the same travel. Best Western, for example, gives its most frequent travelers a 30% bonus on the points they earn; Hilton gives its top tier a 50% bonus, and Delta’s Diamond Medallion fliers get a 125% bonus on the miles they earn. If you travel a lot, concentrating your business on one airline or hotel chain can help you rack up the rewards.

Get the credit card. If you’re an elite traveler on an airline (flying 25,000 miles or more annually), it often makes sense to get the credit card affiliated with that frequent flier program. But airline-branded credit cards tend to come with hefty annual fees, so you need to either travel enough or charge enough to make the plastic earn its keep. If you have one of these cards, do an annual review to make sure that the value of the miles you earn are more than offsets the cost. Otherwise, consider your alternatives:

• Hotel-branded rewards cards are often a better deal; they typically don’t have annual fees or blackout dates for using your rewards.
• If you charge a lot and want the flexibility to deploy your points among different programs, consider an American Express Preferred Rewards Gold card (which allows you to transfer miles to 11 different airline programs) or the Diners Club International Charge Card (which allows transfers to 20 airline programs). For more, read Webflyer.com’s review by clicking HERE by Webflyer.com. Starwood Preferred Guest Card from American Express offers similar flexibility to transfer miles to 30 different programs.
• If you prefer simplicity, consider Escape by Discover Card, which gives you credits to offset travel purchases, and the Capital One No Hassles Card, which offers a better-than-average accumulation rate—1.25 miles per dollar spent—that can be used on any airline without blackout dates.

Answer: Credit card rewards programs usually get watered down over time, but that trend seems to be accelerating as card issuers look for new ways to contain costs and boost profits.

Typically, a card issuer will announce a generous new program and eventually tweak the rules to make miles, points or rebates harder to earn. At the same time, an affiliated airline — reacting in part to all the frequent flier miles being earned by the credit card customers — will increase the number of miles needed for a free flight or limit the number of free seats, making it harder to cash in rewards.

As issuers face high default rates and limits on their ability to raise interest rates, some are responding by weakening their rewards programs, raising annual fees or adding new fees, credit card experts say.

That makes it a good time to review your credit card programs to see whether they’re a good match for how you earn and use rewards.

Plenty of people do manage to fly for free using these programs, but they tend to work best for people who either charge a lot (so they quickly earn rewards) or people who fly a lot, since elite frequent fliers, or those who travel more than 25,000 miles a year with a single airline, usually have an easier time redeeming rewards.

You may be able to make rewards worthwhile simply by concentrating your flying with a single airline and its partners. Having miles scattered in a bunch of different programs makes it harder to earn free flights and makes you a less-valuable customer to any one airline.

In some cases, you can transfer miles between programs: WebFlyer has a mileage converter on its site that can show you possible routes for getting miles from one program to another.

Or it could be that you’re better off looking for a credit card program that offers different rewards. Cards affiliated with hotel chains are a popular choice, since the rewards tend to be easier to use. Or you could opt for a simple cash-back card and buy your own airline tickets with the proceeds.

The countdown to the holidays has begun, and if you’re like most people you’re trying not to spend a fortune this year. If the usual “make a pretty basket of soaps!” advice isn’t cutting it, here are some suggestions that might work for you:

Start later. Shopping all year round can help you snag some pretty good deals, but typically, the longer you shop, the more you spend. Retailers have been saving their biggest discounts until late in the season, so if you can stand to wait, consider doing the bulk of your shopping in one concentrated burst later in the season. (One example: DealNews.com says high-end, name-brand flat-screen LCD TVs were 8%-12% cheaper last December than at any point in November, including Black Friday and Cyber Monday.) Free shipping offers start to get scarce about a week before Christmas, but DealNews CEO Dan de Grandpre predicts you may be able to find free shipping as late as Dec. 22 or 23 at some sites. If you opt to do your shopping last minute at the mall, be sure to bring your helmet and pads.

Have the talk. The easiest way to trim costs is to trim the gift exchange. Many families buy gifts only for the kids, or pull names from a hat, or gang up to buy more expensive presents (which is a great approach for teenagers, mothers-in-law and other picky recipients). Suggest to friends that you bypass presents in favor of experiences—coffee out, a pedicure together, a movie and popcorn.

Use your rewards. Most credit cards these days have some kind of rewards program attached. You may be able to can use your rewards points to buy merchandise, gift cards and magazine subscriptions. If you’re feeling really generous, you can use frequent traveler points to get someone a free night at a hotel, a free airplane ticket or an upgrade to first class.

No “Secret Santas.” The recession should have killed this half-baked notion of buying presents for co-workers and others whose tastes and proclivities you shouldn’t be expected to know. If not, counter with a better idea: the white elephant gift exchange, which is at least fun for all participants. Set a low limit on the amount that can be spent ($10 is good, $5 is better), put the gifts in a pile and give each person a chance to pick. Each subsequent person can pick from the pile or steal from the previous pickers. Hilarity ensues.

Give heirlooms. Don’t wait until you’re dead to pass on family jewelry, china, photos or Great Uncle Phil’s banjo-playing taxidermied frogs. Declutter while you’re still around to enjoy the reaction.

Answer: Opening and closing accounts can hurt your more-than-decent score. That’s why the company that created the leading FICO credit scoring formula recommends we apply for credit sparingly.

At the same time, it’s a good idea to have more than one credit card. Having a “spare” card can be handy if your other card needs to be closed temporarily because of fraud, or if your issuer decides to change your terms for the worse.

Opening a card just to get an introductory benefit, such as a pile of miles, isn’t the best idea—particularly if you would have to pay a substantial annual fee, which is typically of frequent flyer cards, to keep the account open. Instead, look for a card you can live with for a good long time. Many rewards cards offer cash back or other benefits and don’t have an annual fee. You can find current card offers at CreditCards.com, CardRatings.com and Bankrate.com, among other sites.

Behind on your credit-card payments? Your credit score isn’t the only thing at risk. You’re also very quickly blowing up any chance of collecting those rewards that come with your card.

CardHub.com, a leading online marketplace for credit cards, conducted a mini-study that examined the fine print of reward programs for the top six major credit-card issuers.  Among its findings:

• In the last 12 months, 15% of U.S. adults have been late making a credit-card payment. The credit-card default rate in 2009 is the highest since 1991.
• If an account becomes delinquent, all points earned under American Express rewards program may be lost.
• If an account becomes two months or more delinquent, all points under the Discover rewards program will be lost.
• Other issuers, such as Bank of America, Capital One and Citibank, generally will not allow you to earn rewards while your account is delinquent. (According to the survey, Chase did not disclose any information about its programs.)

What’s a cardholder to do?

Face the cold hard facts. Reward programs only make sense if you pay your balance in full each month. If you carry a balance or can’t make the payment on time, a reward program isn’t for you.  If you’re pinched, you need to curb your spending and pay off the debt.

And let’s be clear here: Issuers can change the terms and conditions of their reward programs at any time or for any reason. There’s no notification period. No warning needed. That’s different from the current rules that require at least 15 days notice before issuers change your interest rate or fees. (Under the new law, that notification must come at least 45 days before any changes are made to your account.)

Yes, rewards are super under the right conditions.  Just make sure you’ve picked a card and program that work for you – and pay on time so you don’t blow your bennies.

Banks are expected to look at reviving annual fees, curtailing cash-back and other rewards programs and charging interest immediately on a purchase instead of allowing a grace period of weeks, according to bank officials and trade groups.

No doubt some issuers will try each of those gambits–and then wind up backing off as their savviest (and most creditworthy) customers go to the competition.

Because the card industry is still highly competitive, and will remain so, at least when it comes to attracting and retaining low-risk customers. The only way I can see these threats sticking is if the card issuers collude (risking FTC intervention). While we waited for the lawsuits to grind through the system, we savvy consumers could use debit cards, checks or cash for our transactions–because heaven knows we’re not about to settle for a lousy credit card deal or pay a dime of unnecessary interest.

It’s true that it will be harder for college students to get credit cards, and those with poor or mediocre scores will continue to have trouble accessing credit, as they have since the credit crunch began.

NYT columnist Ron Lieber has it right: bankers’ ominous warnings about the credit-worthy paying the price for this legislation are so much sabre rattling.

Answer: No. Both closing and opening accounts can ding your scores. But the damage is likely to be minimal if you have plenty of other credit.

But the programs are getting stingier as banks try to battle the recession and the credit crunch.

“The banks are strapped for cash. As a result, consumers will have to spend a lot more than they did last year to earn similar rewards,” says Jody Farmer, vice president of strategic marketing for CreditCards.com, whose Web site helps consumers compare credit-card offers from across the country.

CreditCards.com suggests six ways to tap your card’s highest rewards earning potential:

Redeem now: If you’ve earned a lot of points, redeem them sooner rather than later. (The redemption value of points is largely hidden and at the discretion of the card issuer, so the true devaluation of rewards occurs at this stage.)

Switch cards: If you’ve recently redeemed your rewards from a longstanding card, consider shopping around for a new card with a better program. Consider programs that offer extra rewards for the type of spending you do the most — such as grocery shopping, gas and drug-store purchases. Choose a reward that you will actually use and will provide a meaningful incentive.  For example, if finding the time and money to go on a far away vacation isn’t in the cards, airline miles may not be an optimal reward choice.

Go for cash-back rewards: Cash-back rewards are straight-forward in how they are earned and what they are worth. They typically don’t have redemption restrictions such as expiration dates or black-out dates. American Express Blue Cash was the favorite cash-back card among the credit card experts I recently interviewed.

Look for hidden fees: Read the fine print. You might be earning a lot of points or miles but if you’re carrying a balance, you’re probably also paying a higher interest rate or a stiff annual fee — and that negates the freebie rewards concept. Also, understand that your rewards are subject to term changes — with very little or no notice. So keep track of your expiration dates on points or miles so you understand when the system changes.

Double down: To earn more rewards, you might want to add your spouse as an authorized user on your account so you can leverage all of your household card spending and increase your annual reward-earning power.

Loyalty counts: Until it’s time to switch, be true to one credit card to maximize your rewards-earning potential. Choose a card with a low or non-existent annual fee. Then confine your spending to that one card to reap the best rewards.

The Hilton HHonors Surpass Card, just launched from American Express, offers all the bennies of the existing Hilton HHonors card, plus a few, including:

• 9 points (triple bonus points) for every eligible $1 spent at Hilton Family hotels, 6 points for every $1 spent at supermarkets, drug stores or gas stations and on phone, TV and Internet service, plus 3 points for every $1 spent elsewhere
• complimentary standard membership in Priority Passâ„¢,  which gives you access to more than 500 airport lounges worldwide
• automatic Diamond VIP status with an annual spend of $40,000 (Diamond status gives you automatic upgrades, access to executive floor lounges, free breakfast in some locations and a 50% bonus on all HHonors Base points earned

Savvy travelers have long since figured out that hotel cards often offer a better deal than airline cards. It’s typically easier to earn and use points; plus you often get more bang for your buck, since your hotel bill can often dwarf your airfare.

You have to travel enough to justify the $75 fee (although a couple stays in an airport lounge would do that). If you’re not a big traveler, Curtis Arnold at CardRatings.com points out that Schwab and Fidelity have both launched premium cards with an excellent 2% redemption rate (payable into your investment accounts there). Thanks, Curtis!
