Skip eBay, they charge far too much in fees.
Go to Facebook. There are Disney Garage sale groups, Disney Groups, Disney Collector's groups, etc. where you can sell your items with NO listing fees. Just use PayPal as GOODS so that you and the buyer are both protected. I buy and sell handbags this way and save so much over what I used to pay for eBay.
I have not used an auction house before, but that also sounds like a good idea. But I would imagine there are fees there, too.
