If you're looking for 4000 point cards or the Live bundle then you're safe that you'll still find lots in stock. I went early last week and they had a ton of everything just overflowing out of their gaming nook.
Just left the Tustin store. Nothing new. They've got a lot of everything except for the 1600 cards. And no tax.
Btw, some of the cards have Blockbuster tags. I guess these are coming from closed stores.
