[Ace] Sell items only?

[ExpAmethyst]

I've been making a little farming game in my spare time (think of it as a very simplified Harvest Moon). I have a farming system set up and working, but I'm struggling with what comes after that - selling the crops. Is there a way to set up the shop so that you can only sell

certain items, but not buy them? 

In case that doesn't make any sense, what I'm looking for is a way to be able to sell the crops, without being able to purchase them (or even having the option to buy them). i.e. You can sell a turnip for money, but you can't buy one. 

I know you can easily set shops as purchase only, but is it possible to set up the reverse of that?

I believe there are scripts for sell-only shops.

Thanks for pointing me in the right direction! I was able to find a sell-only shop script by Tsukihime
