There are two reasons why the content is not visible or listed as unavailable
on the Epic Games Store
-
Your account already owns the content that's included in the product.
For example, if you purchase Borderlands 3 Standard Edition, you
won’t be able to purchase the Deluxe, Super Deluxe, or Ultimate
Editions.
Note: If you're unable
to purchase an upgrade to a different version of the game, you can
request a refund. If you're eligible for a refund and once it is processed,
you'll be able to purchase another version of the game.
-
Your account is located in a region where the game is not available to
purchase. Region restrictions are handled by the developer of the game, and
Epic Games Player Support can't remove these upon request.
