I am not now nor have I ever been an employee of Overstock!!! LOL
Courtesy of BuyBlue.org:
Barnes & Noble 100% BlueMy guess would be that, like Amazon,com, Buy.com would be fairly red - the owner is a Republican [at least ostensibly], and it's headquartered in Florida.
Powell's Books 100% Blue
Amazon.com, 41% Blue
Also, note that the Barnes & Noble empire includes Bookstop, Bookstar, B. Dalton, Doubleday, and Scribner's.
