Amazon Rewards Customers for Walking Out of Stores

In a scheme clearly devised to give brick-and-mortar retailers nightmares, Amazon is running a one-day promotion on Dec. 10 in which customers can score up to $15 in discounts for literally walking out of stores. Here's how it works: Download the Amazon Price Check app for your iPhone or Android device, walk into the retailer of your choice on Saturday with the geo-location feature on, scan three things you'd like to buy, and leave.

Then, anytime within the next 24 hours you can buy all three from Amazon at 5% off, to a maximum of $5 each. That might not sound like much, but as IntoMobile points out, Amazon's prices are usually lower anyway, so that discount is something of a bonus. Plus, Chris Velazco of TechCrunch notes, it allows customers to see a product in person before buying—something you can't usually do on Amazon. (More Amazon stories.)
