When Best Buy Swipes Your Driver's License, Here's What It Knows About You

The article says that someone returned a defective DVD to Best Buy, who accepted the return but stated that that person 'could not return or exchange any other items, even with a valid receipt' for the next 90 days.

How is Best Buy's restriction not a violation of the UCC's implied warranty?

Why does anyone shop at Best Buy? Ever? I see no appeal to the place and no value-add to spend time there. Obviously, others do though. Curious what it is that Best Buy shoppers like about it.

Actually, Best Buy potentially knows a whole lot more about you from one swipe of your driver's license.

Your name, birthday, sex, height, weight, eye color, address; basically everything that's on the front of the license is also encoded on track 1 and track 2 of the magnetic strip on the card. How much of this Best Buy pulls off (and stores) is a good question.
