All I know is that Compusa has a problem and that is why they are all closing down. I used to love them, but once I had bought a 12" powerbook, a used one though, that got damaged in shipping, they were about the only ones that do work here, the apple store pretty much said I needed a complete replacement and apple isn't much for repairs, just replacement. It was insured for $1000 dollars, apples replacement was 1200 for a new powerbook.
At first, Compusa gave me a quote for 300 for a new bottom enclosure. They were about to close so it wasn't a good look that it received, I came back the next day to have them look at it some more, the said what they did was because they were nice, if I wanted them to look at it some more, it would be $75 for the estimate. From just looking at it you could tell it needed a keyboard also. Then the told me they had already ordered the parts and sent them back because I never showed up for the replacement. This was 18 hours after my first visit. On a Saturday.
How did they order the replacement part Friday night, and ship them back Saturday morning? And then tell me this Saturday afternoon? I don't take to be lied to too well, I made quite a scene that day. They called the police. Before they had the courtesy to ask me to leave.
2 months later, that Compusa closed down. Good riddance.
