I really don't think that I would have realized that Home Depot has cool little converters, wires, devices, and assorted odds-n-ends related to electronics - but they do. I've been looking for a USB card reader for a while and while WalMart and Radio Shack carry products that fit that bill they're usually expensive. Home Depot had one for $14.
They claim that their device reads 19 different types of cards... I only care about one, but those who tinker always want solutions that have more options than they really need. :-)
