I've only just opened my Etsy shop, but I have been looking around for an additional place for my items to be available. Many artists recommended Artfire, so I decided to give it a try. I opened a basic account for now, and if I see that I have a nice flow of traffic and a good amount of sales, I'll be upgrading the account to a paid one.
