Mobile Barcode Scanner
Do you have to do a price check when shopping? If you own a Google phone or iPhone, it's easy. Just download a barcode scanner app, scan a barcode, and see comparison prices from local stores.
You can also scan items using the Amazon app that shows you the Amazon price, and you can save the items on a wish list or in a registry. A great way to register on the go.
