2 Funimation Digital Codes from second hand purchases, which I haven't used / already have a digital copy. So it possible they have been used but as far as I'm aware the only way to check is to actually use them. So if you've got an account already (your still welcome to try if you don't have an account, just might be a bit of a waste of time if there already used) and interested then feel free to reply or message me.
Codes are for:
Goblin Slayer Cop Craft
Also have a none anime UV/google code for Outlander season 1 should any one be intrested.
