ShopSavvy takes every shop in your general area, and puts them right at your finger tips. You can compare local prices, find online stores, and lookup store information.
ShopSavvy actually saved my little brother's Christmas. He had asked for a new pair of SkullCandy headphones, but it seemed like absolutely no one carried the model he was looking for. After checking Best Buy, Target, and Walmart, I decided to give ShopSavvy a try. It literally took less than a minute to find a local store that carried them (Big 5 Sporting Goods surprisingly), and call to confirm it was still in stock.
ShopSavvy is the new Santa Claus.
