If you have some extra time today, you may want to keep your eyes on Woot.com. On a normal day Woot sells one item until it is sold out or until 11:59pm central time when it is replaced by a new item. And not only do they typically sell the item before the allocated 24 hours, they sell the items for really good prices. Today is not a normal day, however, as it is part of a Woot-Off. According to their FAQ:
In Woot-Off mode, a new product is launched immediately after the sellout of the previous deal. There is a half-Woot-life of 12 hours maximum on any product within a Woot-Off that does not sell out. The number of Woot-Off items, sequence, and quantity will not be announced.
So far this Woot-Off has gone through nearly 40 items.
