$37.99 for black DualShock 4 in-store at BJ's Wholesale until 10/15. I stopped in one in Raleigh yesterday and they had ~5 in stock. BJ's is primarily east coast wholesale store. Must be a member to get the sale price, however you can go to customer service and get a 1 day shopping pass to get in on the deal.
$47.99 online, probably still have to pay for shipping.
