Spend $75, Save 30%" offer ends Nov. 19, 2012 at 11:59 PM, Los Angeles, CA time.
Doesn't matter though...their ordering system is broken. You can't even select the shipping method right now, so it is impossible to complete your order. dA hasn't been able to process an order all weekend. Bet they are wondering why there has been no sales.
They should extend the sale tbh so my customers can at least finish their transactions.
