I would LOVE a barcode reader that actually finds items in relevant stores.
Example: I am shopping at target and find a bluray movie for $10. I would like to scan said item;s barcode and have an app check stores like walmart, best buy, etc. so that if it is cheaper elsewhere I can get it pricematched. Perhaps this is already a reality (in which case please point me there) but I have only found barcode readers finding the product on random websites, the only one of which that is usually recognizable being Amazon. Don't get me wrong, an Amazon search is great (if it's significantly cheaper on Amazon I will just order it there), but it would be nice to find local listings for price matching reasons.
