You might check to see if any of your local churches or civic organizations do a semi-annual consignment sale for your outgrown / barely worn stuff.
They are very popular around here, and I have sold at the biggest one in town for over a decade now. It takes some prep work, but I made almost $500 this past spring, and only about half of what I sold was name brand. The rest was store brand in very good condition. They keep 30% plus $5 for advertising/admin, and I get 70% of the money back. It's very lucrative and much less hassle than ebay.
It's certainly worth a look...
