Woot! (first mentioned here) has changed it return policy:
Call the manufacturer of the product you bought. You will likely get a replacement of a new model or better item from the manufacturer. If we still haven’t dissuaded you, email firstname.lastname@example.org with your woot order number, the name of the product you are returning, and the detailed problem with the item. We will respond with return authorization by the next business day. Because we aren’t likely to have a replacement in stock, you should be prepared for a refund only option if that’s all we can do. Know that return freight will be at your expense.
