I saw a case in a store that had a plastic contour back to the shape of the nook touch. It looked like it might have snapped in or something and then it had a cover that folded over the front and an elastic latch to keep it closed. Does anybody know which case this is or if there are similar ones? It was $30 at the store, and want to see if I can find it cheaper online, but can't for the life of me remember what store I saw it in, or I'd go back and look for the name myself.
