Where does 14 come from on the whoopee? You made a suggestion at 13.5 and items were added with the taunt, so that sale should be 13 if it were to be used here, would it not? Either way, it may be better to update the Whoopee with that sale instead, if there are no other sales on the thing.

Here are some sales I found:

The 3 hats that need minis are most likely gonna come under 14, given the sellers on the items, might end up going for less than 12 as well. There's also a seller at 10 on the classifieds currently, so this may need a heavier drop.
