Most swap meets I've seen are anywhere from $40-$90 for a space and that's a one time fee. The 13.9% ebay fee is on every single part sold. So a part that is $400 total with shipping means they're taking out $55.60 on that sale alone. 7 equivalent sales easily breaks that $350 mark. And I've heard they're now reporting anything over $350 to the IRS.
