[resolved][xp] Shop that sell an item only once.

[finalholylight]

I need a script that make a shop only sell some specific items only once.
Ex:
Shop 1: Bronze Sword, Magic Potion, Potion.
Shop 2: Bronze Sword, Magic Potion, Potion.
You can buy Potion many times, but you can only buy Bronze Sword, Magic Potion 1 times, If you want to buy more, go to other shops (Shop 2,then Shop 3 if wanna buy more, etc...)
