There's a marketplace section for selling digital/physical goods here(it's called goods). There's also a place called OpenBazaar if you are interested. Good luck with selling whatever you are selling.
I agree this forum is the best place so far to buy and sell anything with bitcoin or even bitcoin itself.We have some very good escrow to protect your deal and everything that is required to buy or sell.Just open a new thread in relevent section,or buy,bid from already listed items in marketplace
