My favorite app can be used year-round - I have used it for months before my holiday shopping began. I can't hardly imagine shopping without 'Pic2Shop' now. With prices all over the place from store to store and add to that competition from the internet, how do you know you're getting those purchases at a good price? Easy - just scan it!
Pic2Shop is a barcode scanner for iPhone4/4s, Droid & Windows Mobile phones with a camera. Just scan the barcode of the product you want competitive pricing on and in a few seconds you'll have a list of other stores' prices, including online stores!
