Sold for Midnight Whirlwind Yeti Punch

Wasn’t listed on outpost, but I had it listed for 13.

Buyer: https://backpack.tf/profiles/76561198170297598#!/compare/1511827200/1511913600

I immediately sold it to a quickbuyer for a little more than 13 keys, but given the sellers at 10, it would be better to not use that here.

Steaming Milkman Mini:

Most likely sold for ~11.6 keys

Seller’s link shows some keys and metal were involved: https://i.imgur.com/DA1OJuC.png (took a screenshot to show as the compare link is from today and is likely to change)

Only sale that could be traced on the thing that didn’t go to a bot. 4 month outdated and sellers at 12 keys, should be fine to roll with 12 for this thing.

Going with 12-16, as that appears to be what this thing sells for in pure.
