For all the negative things that I hear about ebay:
Local auction houses charge 30% on bigger items, and up to 50% on smalls.
Local estate auctioneers charge 10% to 20%, but you have to have an entire estate to sell. Advertising costs are paid by the seller.
Local estate companies charge up to 30%, I am told, for whole house estate sales.
Indoor Flea Market booths run about $160 a month, sometimes more.
Antique malls charge $80 a month for a locked showcase, PLUS 10%-12% commission, and if the buyer uses plastic to pay, add another 3% charge to the item.
One antique mall charges 50% commission if you want to put anything in their consignment area, but you must already be a vendor there with an $80 a month showcase or a $300 a month booth.
One indoor flea market charges 30% commission for their consignment area, plus $1 a month, but you also need to be a vendor there at $160 a month.
There is also Craigslist, which is free, if you like trying to meet up with someone, and IF they show up, you stand there while they try to beat you down to $20 for a $200 item.
Relatively speaking, ebay is a bargain in the big scheme of things.
