The gear in the Second Hand Shop is all ways in the negative, unless you "New Goods" it to death with donuts. Then you only get a "Surprise Box" that may or may not contain a good item.
Then with said "Surprise Box" you pay donuts to get. It is added to your inventory, to which you now have to pay coin to open.... C'mon.
Can you please revamp the Second Hand Shop so that we care about what is there...aside from "surprise box" items.....
