You can still use eBay to simply establish the market value of your stuff.
Funny how much stuff you bring back when you're trying to make space in the gaming closet. :DThat is so painfully accurate... lol
My experience was that if you sell something for the first time using the "new" (it's been around for a little while now) procedure, it takes a few days to get paid. This is because the payment system waits until the buyer receives the goods, to ensure you're a trustworthy seller.
But, then, after a successful transaction, the system "trusts" you and you get paid much more quickly.
