I've PM'd(Brandsmart price) at CC before for an LCD. All I had to do was tell them the retailer and what they were selling it for. Then they do some kinda verification/mgr okay? Something like that. Anyways, I didn't have to bring anything in.
I have a cpl of Brandsmarts around here, but sometimes I just like getting my stuff at CC for the PM deal. I was also looking at the Samsung blue-ray player(thinking of getting my bf one instead of the ps3 since his Nintendos already take up his time!) and I saw they have it at BB for 399+7 movies, and I checked brandsmart last night and they have the same player with 8 movies for 288 or so. Awesome! 100 bucks cheaper and another movie!
