I wasn't sure if I should PM Justin or post here, so I posted just to let everyone know. There appears to be a bug with player shops - a wooden door player shop will always give the error message "Out of Stock," even when the chest contains the door. Daddydaycare assumed this was the case, and came to my store to see if it was the same for me. It was, is this a bug just for SMP2 or everyone? Details: SMP2: My chest full, daddy's full also. I hope this is enough information, - Alex.
Type in the ID : 324 / "wood door" in the last line instead of "wooden door". Somehow the shop doesn't recognise a wood door as "wooden door".
