It's fairly simple.  Best Buy stores are nicer and cheaper than Circuit City stores.  Circuit City is the Dominos to Best Buy's Pizza Hut -- reliably discovering new degrees of awful vs. hardly five-star but at least consistent.  The stores are filthy.  The company chooses terrible locations.  (If you want a big-box retailer on the outskirts of town, the company's name had damned well better be either Wal-Mart or Target, or your competitors are going to rip your face off.)  Find me a product from Circuit City, and there's a better-than-decent chance that I can find it at CostCo, and I'll find it cheaper and sold to me by someone who doesn't give me a fucking attitude throughout the process.

This has nothing to do with pay and everything to do with idiocy.  The CostCo employee is (now) making a lot more than the Circuit City employee, and with benefits, as I understand it, yet CostCo still manages to compete well enough against a much larger adversary (Wal-Mart), while Circuit City has its clock cleaned.

Neither one carries Mac stuff, so fuck'em both.  I'm limited to CompUSA in the big-box electronics market.

Be nice to America. Or we'll bring democracy to your country.
