RTF stands for "Random Things From", thus this store is called "Random Things From Lunaris"

Just contains whatever i may have to sell, usually transferable things like gacha vouchers.

As most things here are gacha vouchers or the like, all sales are final.

For that same reason i cannot help you if item was not received or there is an issue with the gift card.
These are nearly always no-copy, meaning once you receive them i do not have it anymore to redeliver, or give another.
They are from someone else, i have no control over their delivery.
