I've been finding apps for you guys for over 2 years now. Since I'm negotiating apps all the time, I tend to do it for other things as well
At the supermarket: "$2 for this drink? No, I want it for FREE! As you might guess, the only thing I get for free is an invitation to leave the shop.
With Shopmium however, you can do that. They negotiate deals for new products coming into the market, and give you a large discount on the product. All you need to do is take a picture of the receipt!
At the moment, I'm going crazy for these Oreo crème filled cookies, as you get $1 back, but there are many other deals out there, so make sure you don't miss it as Shopmium is 100% FREE!
