CompUSA hasn't closed yet, but people are already writing an obituary of it. whether it was Mexican Entrepreneur who could not turn it around, or if it was the competition, one thing is true. CompUSA did not provide great service to its customers in its last days. All the visits to CompUSA that I had done before they closed in Atlanta weren't really great (Well, I do not have good words for Circuit City, Micro center and Best Buy either). I always found that they had parts costlier then many of other stores (not the web price).
I am not sure if Circuit City and others are reading this event closely and making changes. If not, they would meet a similar end too.
