No wonder I couldn't get logged in to grab one of the $100 Xbox 360s from Amazon.com... 

From MSNBC.com:

"We saw dramatically more traffic than what we anticipated," Amazon spokesman Craig Berman said Friday.

The Xbox sold out in 29 seconds, Berman said. Amazon also sold out of discounted Mongoose mountain bikes, Barbie dolls and Amazon Prime memberships with $100 gift certificates in about 15 minutes.
