the seller who sold to you for 170~ first purchased for 180, but there's another sale at 170 with the help of the buyout.

145, 170, 170, and 180. since 180 resold for 170, those can be excluded, and since we're excluding sale at higher, could exclude 145 too, conveniently 170 would work here, but 145-180 could also work (including all sales). up to the mod.
