Ruth, the home cheapo around here carries them. They have a universal one and then some doors come with separate add on kits. Go talk to the people at the order desks (where they have these 4' long rows of catalogs) and I'm sure they can order you one. You might have talked to one of the stock boys/fork lift drivers who was too busy banging and denting the doors while stocking the shelves.
I sometimes look around for the scratch and dent items, find the manager, and then get a substantial reduction to take it off their hands before the public sees the substandard merchandise. I asked a lady a while back if a scratch would keep her from wanting a $700 patio door for $100. Saving $600 was noooo problem with her. Since you are from south florida, maybe whoever you talked to was too preoccupied with this Alien/Elian fiasco to look around.
