There were 221 CompUSA Stores.  I got the cached page from
msn since google didn't have it.  Green is open, red is closing.
If there is an error maybe I'll get to it sometime.
This was output from Excel because I am lazy.  So the HTML is shit.  Sorry.
Thanks to a digg pointing to an article on controlf12, I've linked
the state names to webarchive so you can get the cached page
and the address/phone number without more searching.
