An Amazon Wishlist can be set up by models. Add items to it and put a link to it in the Chaturbate BIO where generous Chaturbate users can go and buy the items for the model.
When setting up the Amazon Wishlist you will have to provide an address where the bought items can be sent. This address will be shown to the user who buys the item so it is a good idea to set up a PO BOX where the items will be sent.
