All versions of Barcode Scanner - Price Finder

New set of features: price history and price tracking. Please note that this is our initial launch, and the availability of these features is currently limited: 1. Currently limited to premium/free trial version of the app (will be made available to free version when our server capacity allows.) 2. Limited to USD - other currencies are coming soon. 3. Setting low price notifications is not yet available - we are working on it.
