No joke, it really will. All you have to do is walk into a retailer this Saturday, whip out your smartphone and use Amazon's Price Check app to collect price data on in-store items. In exchange, the company will offer you a discount of five percent (or up to $5) on "select items" in electronics, toys, music, and other product divisions, though you'll only be able to use it a maximum of three times. The campaign represents Amazon's latest attempt to creep into the brick and mortar sector on the back of barcode scanning technology
, and seems like a pretty clever way to bolster its mobile presence, while gathering intel on its competitors' prices, as well. It all kicks off at 9 PM (PST) on Friday, and will draw to a close just before midnight on Saturday. Hit up the source link for more details.
