Discover Cash Over is an often overlooked but very useful feature that allows you to use your Discover card much like an ATM card at the grocery store checkout. When you use your Discover card at a participating supermarket, you can request additional cash at checkout, and it will be treated as a normal purchase with the same APR and grace period and no transaction fee. For those who pay off their balance every month, it’s a convenient way to save a trip to the ATM.

In the past, the program was even more attractive, since you used to be able to earn rewards on the cash you received. That was like getting free money. While most stores no longer give you rewards on your Cash Over, there are a few that still do.

It’s unclear how long it will remain the case, but for now, you’ll earn 0.25% on your Cash Over at discount and warehouse stores like BJ’s, Sam’s Club and Wal-Mart. Note that 0.25% is also the amount you would normally earn on purchases at those types of stores.
