So sales in order

60 (untrace tho) --> dump to stn --> 70 --> dump to qs.store (42)--> 69 --> bulk --> 72 on mp (no buyout)

With so many buyers either dumping for way less or in bulk shortly after, I don't think a range with just the high sales would work, especially since the would-be low end of 60 is untraceable. I would leave this outdated.
