eBay has become a show place for jerseys sellers. It's not really a selling tool anymore.
I see jerseys that have been isted 15-20 times always for the same price that never sell. Sellers seem afraid or unwilling to work outside of eBay. The casual jersey seller doesn't know or care about the various jersey boards, forums, Facebook sites, etc that could save them loads of money in fees and at the same time lower the sale price to something more in-line with what a buyer would be willing to pay.
I have bought one jersey off eBay in over a year and unless I get a true steal don't see it happening anytime soon.
