Amazon.com today introduced a promotion that allows customers to collectively choose which discounts the site offers during the holidays.

For the next four Thursdays, "Amazon Customer Vote" offers four deals at dangerously low prices, but customers can only select one.

Voting closes the following Tuesday, with the deals announced that Wednesday.

Today's choices include an Xbox 360 Core System machines for $100 or a Barbie Interactive Princess for $10.

This not being a democracy, the deal items will be offered in limited quantities.
