Hey @DaddyShark for your hat, be careful enabling minting on in world vending machines if you set the price as FREE - there is poor controls over users claiming multiple items. A few things you can consider:
Mint all the hats to your wallet before you enable vending machines
or, Mint all the hats to the destination wallets before you enable vending machines
or, Set a price to the hat if you want the other items to be in the vending machine
