abstract:A rebate card is a debit card that provides funds promised by a business as a rebate. They are often offered to those who make a specific purchase, or for loyalty to a company by accumulating a certain amount of money or number of points worth of purchases from a particular company.
With Amex-Foursquare, you link your credit card to your Foursquare account and then check in using Foursquare at a designated merchant and get a discount or rebate applied to your card.
We've crunched some numbers to illustrate how, for those who carry a balance over each month, even a better-than-average rebate can leave you no better off than a low-interest rate card.
