ItemGains
Reduces the tooltip value "materials gained" by the cost of the item when you buy them.
I feel it better reflects the actual money gained for these items.
Affects
* Bag
* Hunting Trophy
* Metal Detector
* Piggy Bank
* Recycling Machine
Example: If you buy a metal detector for 40, the money gained for them starts at -40, since you spent money getting the item.
You might also be interested in the related mod "ItemSavings" which does the same, for items with a "materials saved" tracker.
