Cataclysm-dda: (Nearly) Infinite Money Exploit

[friendfrog]

Describe the bug

Cash cards have the same value regardless of the amount of cash in them. This value is always more than the cost to purchase a new cash card from an ATM($1.00). You can buy large amounts of cards from ATMs and trade them for items worth more than 4 to 8 times what you spend to get the cards(Depends on barter level).

Steps To Reproduce

Steps to reproduce the behavior:

1. Find an ATM.
2. Buy as many cards as you can with your starting bank funds.
3. Trade them to a vendor for more than you paid for them.

Expected behavior

Cash cards should be worth less than or equal to what you pay for them, or be worth however much you have loaded on the card.

NPCs no longer trade with money (that is not faction specific), they barter, so this doesn't exist on more recent versions of the game.

I am using the most recent experimental version.
Here's an example of what I can do with 0 barter and a stack of cash cards traded back and forth.

The cash cards are worth 20 cents when owned by the merchant but I can trade them for 4.10 each.

It's tedious but I can eventually clear out their entire inventory.

We can reduce the value of cash cards very easily.
