Yeah the thread is specifically for Castlevania Fans to sell/trade their stuff to other fans.
Sometimes you have to, for whatever reason, give up your Castlevania-related wares & swag. At the very least, with this thread, in this forum, you will know you will leave it with another fan of the series, as opposed to leaving it with some stranger.
I suppose you can bypass eBay with this, but it's not an auction house. Ideally, one would use this thread in conjunction with Private Messaging and perhaps Paypal, and talk to your purchaser, more along the lines of how Craigslist does it.
I hope that helps.
