I'll just say that the stash definitely needs a mini since it's gifted.

Didn't bother to look at the prices of the other unusuals.

did you calculate overpay?

"should" is not a very good word for this kind of thing

definitely needs more minis because it has not yet been involved in a sale with significant amounts of pure, only sales trading unusuals for other unusuals

Lots of minis needed. The Fez I had is outdated and there have been a couple of recent sales, I bought it for 6 pure (supposedly a quicksell, but from what I hear the seller had been quickselling for a while). The Stash was gifted and a mini is needed for that. The Outdoorsman is 8 months outdated. The YWN and Stash are 3 months outdated, don't know if they are useable at that time period. And you applied no overpay.
