Looks like a missed dump to STN, as the seller receives nothing in this compare (mostly due to date mismatch), but outgoing keys from buyer are to STN.

Sale 1: 42k outgoing, 11k incoming to an STN bot supporting the above theory, but the full amount is still unknown, and taking sale as-is at .5k above buyers would drop low end significantly

There's an 15 item bundle with 11k and 4 misc items, but could've been more that was dumped due to the volume of outgoing, can't discern full value so excluding as an incomplete sale.
