Sometimes the bottom line rules, and the simple fact is this: Best Buy is the cheapest place to buy compact disks. Super-mega-monstrosity-chain store or not, it's where we turn for the latest music. New arrivals? Always $11.99 or $12.99. Everything else in the store? You won't pay more than $14.99. Just about any other music emporium (the other megachains included) will tag you for $16.99. That's a two-dollar chunk of change we'd rather spend on a blank tape or bargain-bin cutout. The selection at Best Buy is comparable to any store in town as well. In recent months we've picked up Robyn Hitchcock's latest, Storefront Hitchcock, and the Pine Valley Cosmonauts' Salute the Majesty of Bob Wills, a tribute album featuring such altcountry luminaries as Robbie Fulks and Alejandro Escovedo. We even picked up a digital version of one of our scratched-up old vinyl stalwarts, The Replacements Stink. Now that doesn't stink at all.
