If the cost of shipping is prohibitive enough that you cannot sell your items on Ebay for an acceptable price, that seems to only leave local options. You mention that you got a lot of low-ball offers on Craigslist, but that is not unusual. Finding a buyer often requires a long wait, and this is true of most all venues. It does not sound like you live in a remote area, so if the items are priced within reason they should sell eventually on Craigslist, etc.

Thanks for your quick response guys. I was just hoping that there was maybe a better place where people can sell decent good modern furniture without having to wait for ever. During my research, I found this website http://www.lushpad.com/. Anybody here that ever used it?

Depending on
what you have, i.e. if you have some really nice things, I would consider Brimfield. If you have good stuff, you'll sell everything in your van.
