I think I might have a real problem. My kids are scared to leave anything out - Mommy might sell it while they are at school. 
I just sold a used hot wheels over-the-door case (discontinued - like this one... http://www.amazon.com/Wheels-Over-Door-Display-Case/dp/B000MAJIG0 ) for over $50.
I paid $8 for it, like 4 years ago.
My son wanted a DS for Christmas. He told me that it was "ok if Santa bought it used". My heart broke over that one, so I was bound and determined to buy him one. I ended up buying him a DSi during the Amazon preorder - got the DSi, the Mario Party game, and a $25 video game credit for $150 - no shipping, no tax. I sold the Mario Party, plus two "lightening deal" games I got with the credit for $65 - so my out of pocket cost for the DSi was $85.
(DS had a DS previously that broke, so he has games.)

I've had great luck with the free section and passing stuff along though, sometimes the stuff we posted has been gone within the hour!
