This is a fantastic resource for those of you looking to sell your Barbie collection. You can post links to your eBay auctions, DollPage listings, Craigslist auctions and other for-sale listings with photos on the Barbies4Sale blog.
You all should subscribe to Ken's blog, too--first, because he's a great guy. Second, because you're bound to find something you "need" for your own collection on here. And it's free! Both to post and browse. You can't beat that.
Give it a try. And don't forget to click on the ads while you're there. (It's only polite.)
