This mod doesn't seem to work in my game. Every time I play a shop, my playables who visit it end up will all kinds of things they've bought in their inventories which I end up having to delete the next time I play them. Also, their funds are diminished because they can't sell the stuff back for as much as they paid for it. Maybe I don't understand the scope of this mod, or perhaps I have a conflicting mod somewhere in the mix.
update:
Found the culprit and deleted it! The mod works great, and clears up a huge nuisance. Thanks dude!
