Smack in the middle of Omaha, NE, it's the largest single home furniture store in America. And, at 415,000 sq ft, I sure hope so. Need to comparison shop? No problem -- they carry every brand of everything -- appliances, computers, sofas, DVD players. The store is out of control.

Founded by the infamous Rose Blumpkin, it is now owned by Berkshire-Hatheway (i.e. Warren Buffet).
