You could post them for sale on the SewItsForSale group on Yahoo. There is no commission cost that way. Just be sure to read the FAQs they send on what you can sell and what you can't, and also how to post (and remove) photos correctly. It's quite an active list. Here is a link to it:

To join the group you need to set up a Yahoo ID (if you don't already have one), but it's free.
