====== Stashing inventory ======

This mod will let you 'save' 3 (or whatever #) pieces of inventory of each item. So if the true inventory is 50 pieces, the store will act like there is only 47. This will let you keep a stash around in case you need extras to replace customer's damaged or lost packages, or if your inventory is off by a few pieces.

For example, we have 83 Mintyboosts in stock:

But the cart displays only 80:
