This list is great, thanks! I wanted to point out, though, that it looks like at least some of the transcription jobs are listed as paying per audio hour which would work out to a lot less per hour of work. One hour of audio can take 3 to 4 hours for an experienced transcriber to complete, so $24/audio hour=$6-8/hour. Just something for people to be aware of.
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!
