The Consumerist:

Customers will have to prove that they’re over 21 in order to buy a prepaid card to use in the beer-o-mat. The machines also limit the quantity of beer that customers can purchase, limiting them to 48 ounces every 15 minutes. You know, in case a group has dispatched one person to get beer for everyone.

Those 48 ounces of beer will cost $18.24 if you buy the cheapest selection, Bud or Bud Light at 38 cents per ounce.

I heard The Publisher of The Loop is starting a Kickstarter campaign to set up one of these full of Heineken in his house.
