6. ShopSavvy
ShopSavvy works on a pretty simple but unique idea: if you like a product in a store, you can take out your smartphone, open the ShopSavvy app and scan the barcode of the product. The app will compare prices from different online stores within seconds. Based on this price comparison, you can make the best buying decisions. ShopSavvy also notifies you about daily sales, deals, coupons, and cash back offers from famous brands and online retailers. ShopSavvy also has a review system for products, so you can check how others value the product you like before actually buying it.
