Sale 3:

Sold for Smoking Napper’s Respite

No outpost

Only sale I could find on the nappers was around ~26 keys worth (with no visible B/O), which seems a bit high with a seller for 19 keys on the market. Would be better to use this sale to update the napper’s.

Milkman Mini:

Sold for 18 keys?

I’d assume the seller bought those items with the keys from the trade, which is why the keys don’t have the seller’s name in the history. There aren’t really any other proper sales on the item, so this should be fine for the milkman.

There’s also a seller for 18:
