I made a mistake and bought an item for my sub. Can I return it for a refund?

As the items are no-transfer, there is no way for you to return the item. And the automated update system means that because you purchased the item, you are eligible for all future updates. These factors make it impossible for me to give a refund, sorry.

That is why I have several warnings on the vendors themselves, and at various locations in the notecards.
