I wouldn't know, haven't been in a CompUSA for 7 years now.
The suckers shrink wrapped an old, used video card that was a different model in a new box and sold it to me as new for $399 and when I took it back the manager accused me of lying and trying to scam them. One of their employees said they were not surprised because they had a shrink wrap machine in the back before the manager came out to talk to me.
If you ever buy something that expensive in a store, open it up in front of the cashier before you leave the store to avoid this kind of thing!
