Some scams might involve asking you to pay for a “training” book or CD that explains how to make money in a certain business. Others charge for supposedly “exclusive” products that you’re supposed to sell at a premium. Avoid both of these scenarios. Remember, you should never have to pay to get a job. And if someone asks you to, you can be sure that it’s a scam.
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!
