So, I have taken a script that stocked scrolls on a vendor and cut most of it out to where it will stock in this case Granite stacks,
My problem is this if i do commodity deeds, it puts the item exactly where i tell it,  But since i switched it over to stacks it just drops the stack anywhere in the vendors pack.
this is for uo shard
Here is the script
Thanks Pendragon
