I went to the Once Upon a Child in Largo and it was a big mistake. It took them forever to "price" my stuff. I had many many new in package clothing items and toys. All told, they offered me less than $50. I had been waiting over an hour for their "price" and after waiting that long, I didn't feel like taking my stuff back.
In my opinion, you will get a lot more money if you post on craigslist. Plus you don't have to wait in a store while teengage girls promise you "just 10 more minutes" and then ignore your stuff.
