Two sellers below the high dupe sale, both also dupes

Given the previous failed attempt to raise this based on a high cash sale, which was later dumped, going to say a conservative raise to 350 (based on the physical sale) would be better here. The lower dupe sellers also suggest that sale is an outlier.

Taking 350 flat.
