Consider where you shop. Save your key ring or wallet space for cards that will earn rewards at the stores you use most.
Project your spending. Translate the amount you're likely to spend into cash back or points, depending on the program. If it's points, find out
how many you need to get something you might want. If you're using a credit card, subtract the annual fee, if any. If that
calculation shows you'd have to spend a fortune to earn a pittance in rewards, you might want to forget that card.
Favor cash back. You might never redeem your points, so at least you will get something. Plus cash-back cards tend to be more generous in
their rewards, our research has found.
Skip credit if you carry a balance. As the tables on the facing page show, rewards credit cards often charge relatively high interest rates, which will eat up
your reward (and then some) if you carry a revolving balance. The issuer can also hold your points hostage or stop adding
to them if you pay late.
Do the math on do-good programs. Cards that give your reward to a charity usually pay about 25 to 50 cents for every $100 you spend. And you can't write off
the donation on your taxes. Both you and the charity might do better if you use a more generous rewards card, keep the money,
and write the charity a check.
Use airline miles fast. Cashing in frequent-flyer rewards has become more difficult because airlines have cut flights and now have fewer seats available.
So rack them up and use them up as quickly as possible. Airlines also change their rules frequently, and several big carriers
have recently gone bankrupt.
Avoid temptation. Research has shown that people who use rewards cards charge more. It's easy to overspend just to earn a new digital camera
or set of golf clubs. Beware.
