These are the sites that I use to sell my items on. Yes there are others but I use the sites listed below.
I sell on my own personal site.
All Things Worn Lots of changes have taken place on ATW. Be sure to read their TOS and any blogs on their site talking about the rules there.
Snifffr I am no longer on snifffr. They are a legit site but I decided to go with the sites that work best for me. The problem I started to have with sniffer is that people were starting to leave fake reviews. The admin team is REALLY good at getting them taken down but I personally will not deal with fake reviews from anyone.
