Hello, I would like to trade a few items to make some money for accessories for the Nintendo Switch that I pre-ordered but I have a few questions. 1. How does shipping multiple trade-ins work? Could I just put more than one game in a box? 2. When you trade in the game, does the money you get go to your Amazon account or does it go to your bank? 3. Anything else I need to know about Trade Ins? Thanks.
