The Dealers' Den, Artist Alley and Art Show are primarily for artist and dealer. Dealer sometimes do sell stuff they don't made themselves, like books or plushies.
If you have just one Fursuit to sell cause you either need the money or don't want to wear it anymore, why not offer it at FA or here at the forum with the option to bring it to EF. Then you don't have the stress with all the set up and more time to party.
