I found a 6x8 leather agenda on a website that someone is selling for $30 (yes it's real!) I was wondering if anyone had one? Could you take some size reference pictures? Maybe next to a DVD case or a piece of paper or something? Also, would it fit comfortably inside a medium ergo hobo? (if not, that's okay) Oh, and where could I find refills to fit one other than the Coach website? Thanks ladies!
