You need to take them out of your vault and turn them in here. The token vault is separate from the actual item vault.

Sorry! I think I get what you are saying now. The Token Shop itself only stocks at certain times. So if you don't see anything in there, then it is not stocked right now (which it isn't). They will post to the news when it is going to be stocked and it usually stocked 3-4 times with those items.
