CompUSA is apparently closing shop, something that is not too surprising observing the follies at my local store. I can understand how CompUSA was killed by the likes of Best Buy and Fry's Electronics (not to mention Newegg.com, which is my favorite source). What I cannot understand is how Radio Shack continues to plod along and survive. I buy a couple of things a year there (usually something like a transformer replacement or some kind of oddball splitter) but I am always kind of surprised to still find them there -- its like finding a Woolworth's in the local mall. Though it still seems to make money, with a TTM after-tax margin of about 5%, which is not bad for a retailer.
