Store credit cards such, as the Staples More Account card, are fairly easy to understand; you use them for online or store purchases at the particular retailer.
The Staples card could be considered no frills. It doesn't offer cardholders many bells and whistles but comes with a flat 5% rewards offer on all store purchases. It's a pretty decent rewards rate -- you could fiddle around with revolving categories on cashback credit cards without achieving 5%.
The rewards are not redeemable for cash. They're automatically issued each month in $5 increments for your next purchase. It's important to stay on top of your rewards -- they expire in one month. If you don't apply them to your store purchases within the short window, they're gone. While this strategy is a clever way for Staples to get business card customers to shop at the office supply chain regularly, it's inconvenient for smaller businesses that may not make Staples purchases so often.
