Buying a product in a store, you have doubts about its cost, because it seems to you that you have already seen it cheaper somewhere? Don't go shopping to check the price! Just use this magical QR and barcode scanner. It will show the current price of the product, indicating the addresses of the stores in which the product is available. If the item is not found in the database, you can help other members and add it. Add your stores, so as not to remember in which of them the goods were cheaper!
