Agreed. This one comes off sort of like a marketing scheme. I ordered at 7am and like you, no word from them on my cancelled order for a day or two. My local store was had no stock (1000s) before the sale.
Draw the customers in with limited stock, mark it down to whatever you want, doesn't matter even if they sell below cost since their stock is so limited it doesn't make a dent. Oh well, would have been a spare for me, having the money is fine too.
