Doubt it. Like I said before...the gift cards would have been the biggest hit. Other products (depending on mark-up) would have varied.
Yup - a lot of items, at half price, were still at or above prices I've seen on Amazon. GC - for sure - that's not going to be nice on the balance sheet.
Otoh, I was looking in music - saw the same Heart box set I got before Christmas for $20 - they had it for $39.95. Likewise a lot of games and blu rays. I told my son about the "deal" - he replied "So what - most of what they sell is double price anyway."
NOT saying there weren't a lot of good deals to be found - but I also doubt if this will put them out of business. More a case of a one day January inventory clearance sale.
(me - I played nice, picked up a 2tb usb 3.0 hdd for $49.95. I was going to get the 32 gb Vita memory card, but like a fool, saved that for today.)
