Only buying one quantity of an item

[shanachiba]

Good morning. (Or afternoon, depending on your location.  )

I'd like to make a request for a shop script that would allow the player to buy only one of an item. (As an example, if you've played EQ2, a Lore item.) I need this because my game has the player buying a quest item. I don't want them to have more than one because of some event switches. I've seen the shop script for buying or selling only, but it doesn't include an option like this one (that I saw.) If someone could help me out, or direct me to a place that has one that I couldn't find, I would be very appreciative.

Thanks.

That's an awesome script but . . . I'm an absolute moron when it comes to understanding how to program it. Can someone translate the instructions into laymen's terms?

Could you not just use an event?
