Has anyone used Co-Operative Consignment before?

I've been asked by a seller from Craigslist to do a deal through Co-Operative Consignment but I have never used them before. They look pretty legit to me, but I need second opinions. I'd appreciate the answers.

Update: Considering all answers, I went on with it and we now have a new camper! The camper was as advertised so we don't need the 10 days! This was way better than expected!

Thank you Liberty Consignment! Totally recommended!
