Unpriced, counter suggestion. I spent more time formatting the suggestion than looking up these apparently untraceable sales.

Sold for 1 key + Green Black Hole Bucket Helm (~2.25) = ~2.3

No change in backpack, assuming it is the $97.77 CAD sale on SCM, dates match up nicely and they say in the trade its on SCM anyways.

From other suggestion;

"

Sale 1: Sold with a clean max's (3.3) + a bud in keys for a c9 hong kong cone (5.9)

5.9 - 4.3 = 1.6 Falkirk was offered on the cone so I don't believe it needs overpay.

I can't use what I paid for it because I paid with an unpriced hat that was quicksold to me for a bud.
