While many credit cards have innate earnings programs, like the Membership Rewards program from American Express or the Unlimited Rewards program from Chase, there are independent programs that give you points, miles, or straight cash-back.
Doctor of Credit has put together a fairly comprehensive list of these programs. While I frequently use Thanks Again and various dining programs, I hadn’t considered stacking it with IDine! With the frequency I dine out for work, it would make a substantial difference, I think.
A lot of stacking comes down to trial and error, though the page above has a few sites that are known to share back-ends. Programs that share back-ends won’t allow you to stack, while those that are independent of one another (Thanks Again, AAdvantage Dining, and IDine, for example) are more likely to. This is in addition to anything the card earns on its own, of course!
What about you – do you belong to any of these programs?
