Kinda bulky, and doesn’t really favour any hat here. Probably better to not use this sale at all. Would end up being around 30 keys, probably.

Buyer at 17 keys: http://i.imgur.com/cSfbvNr.png - Excluding 17.

Excluding 19, because it’s a gross taunt sale.

If I were to get an exact value from sale 4, it would be close to around 30 keys, which would be a bit of an outlier.

Going with 21 flat.
