AT&T is selling off their first generation iPad cases for $5 with a 25% off code right now as well as free shipping. This includes companies like iFrogz, Incipio, Speck and Otterbox. I think they allow you up to 4 of each case. I am getting a replacement Speck Plaid case for my wife who messed hers up as well as Otterboxes for both of us.
