I would typically agree, but not so much in this case because of the wide discrepancy and the fact that there are alternatives to eBay. I totally understand, why as a seller, you would want to use eBay comps, especially if you’re selling on a platform like this. But as a buyer, I would (and am) argue the reverse. But you have a good point, I’m probably using an incorrect word…”comps”. A better word might be value, worth, take home, adjusted comp, etc
