Hey guys! Been a while! As the topic name says, I need help with making a system that refunds a gadget. So far, I’ve made it so that the player starts with one cash, and that all the gadgets in the game are one cash as well. I am worried that players would abuse the feature to get more cash. Or am I simply over thinking this?
-Side note I am leaving for practice shortly so I will not be able to reply to any responses for a while. 
Do you mean you can return a gadget to get cash, or you can get your gadget back after selling it?
The player is in a shop where they can access any gadget. So even if they sell it they can always get it back.
Also I GTG. TTYL
just have another vending machine that triggers others and each try to buy a gadget in return for money
I would make a machine that allows players to return an item by inserting it into the system.
This way, people can easily return unwanted items and use the refunded item to buy something else. It would make buying more convenient and make the person happy 
you could implement a cool down to make it less explotiable
I don’t understand what part would be “exploitable”. If you spam what @DuhDinoKing2099 said, then you would have either 1 cash or a gadget, but you could not get infinite cash or gadgets. I thought what the OP meant was what @DuhDinoKing2099 said.
Ohhhh yeah I get it. I was overthinking it. Thanks a bunch guys!
