I think that mostly looks high because that headwarmer doubled in price (slightly exaggerated but you get the idea), when that same person bought it. Sellers on the jefe have always been much lower. Currently, theyre at ~220 which would support it being nowhere near 290. It seems ~290 is an outlier here, or an indication that the headwarmer is too high at current (or both).

I see a fairly substantial gap between buyers and the two sales posted here - I think 160 is a decent pure estimate for this suggestion to work with.
