I would save them for a consignment sale. Kid to Kid probably won't take most of your stuff, depending on what you have and you won't get much for your effort I have found.
My favorite consignment sale is the Just Between Friends sale in Fort Worth. The spring summer sale is the next one. It is in March, I believe. You can go to jbfsale.com to find out more info.
I have consigned several times now and am planning on continuing to do so. I always make enough money to buy whole new wardrobes (including shoes & sometimes toys)for the next two seasons, for both of my kids. Of course I buy their clothes at the sale. The women who own the Ft. Worth one, Joanie & Pam, really have it together so it is not too hard at all to consign. You get to shop early if you consign too. I volunteered last time and got to shop even earlier. That really is how you get the best deals!
If you decide to consign, I'd love it if you would put me as your reference because I can make a higher percentage that way. Just put A. Myers #3252 as your reference!
Good Luck!
