I've been introduced by my friend last spring. I've got 4 checks from them, last time I got $23 and I don't even shop that much. I like that it's easy, I downloaded the app on the phone and the bar on my PC. When I get on the website from my PC the pop up window comes up, you activate it and shop.
Sometimes they'd have a double mobile cashback, then I'd shop it from my mobile.
Also you don't have to look for coupon codes. Ebates button on the PC finds them and lets you know that there are available coupons, all you have to do is click on Apply.
