I saw an article about a keychain type device where you can scan a price (ie: in a grocery store) and it will let you know if that item is selling anywhere within so many miles for less. Anyone know what this is called and where it can be bought?

Someone needs to maintain a pretty hefty database of all prices in all grocery stores. I am not even sure why a supermarket would provide their prices to a 3d party!!
Just go to Costco or Sam's Club.
