The best part, as soon as you choose to cash out, you'll receive your rewards instantly online through your PayPal account or with gift card claims codes from online marketplaces. There's no comparison between receiving rewards electronically or via check, which is still the gold standard for most workplaces and even some other online pursuits. Instead of waiting a week or more to receive a check and deposit it into a bank account, you'll get your cash at a lightning-fast pace.
What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
