We deliver items face-to-face in the game. Please give us your Fortnite display name and Epic games email address, and a supplier will send you a friend request. You accept the request, and the supplier will group you in the game and drop what you bought, then you pick the item(s) up.
For PS4 and Xbox One players, before you place an order, you need to make sure your account automatically accepts friend requests so that you can receive a friend request from the supplier.
