I tried to cancel an order 2 minutes after I placed it with Woot. This was well within the 15 minute window. After clicking cancel the top of the screen displayed my order and said it was ordered 2 minutes ago. The bottom said cancellation could not be completed because it had been past my 15 minute window. Very shady and disappointing. As others have stated they charge you 15% restocking and you lose your shipping concession and have to pay return shipping. This is how they steal. BBB will be notified.
