These mega-sites make it easy to set up shop so customers can browse your products, and there's no need to build your own website. Also, you’ll find a built-in search feature so that interested buyers can easily find your online storefront. Plus, you get to use the site's shopping cart. In short, you avoid a lot of the expense and hassle of setting up an independent e-commerce website.
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!
