My Android phone has an app that does a bar code scanner that can eventually
look up the product it scans online to see who sells it for what. I've found
prices for things when looking up some very boring, unimportant things when I
tested it around the house. It has however failed me twice in computer stores
when I was hurriedly trying to find out if the price were right. I quickly
scanned one of the five or six bar codes on the box and it never worked. Maybe
some of these were about the UPS shipping or inventory. I never found the store
product UPC.
