Now just remember that this one is just for California. You can narrow down your search to any major city or state in US. It is a blessing for people who want to get rid of their old items. Now, thanks to this site, they can hopefully exchange it with something which will be of use. They call themselves "we are a new site battling with the big boys and growing VERY quickly". Let us see how well they will live up to the expectations.
