The site is just starting up, but you’re welcome to post your works and sell them.
Commerce is handled by Fotomoto. You will get your own shop dashboard, where you can set prices and decide which products to sell. When a customer orders, you just upload the original file via your dashboard. Fotomoto then prints it and delivers it to customer. You will be paid via PayPal or credit card, right when customer pays for the order.
I hope you will enjoy this new option to broaden your online presence. In the meantime, I’ll be looking for more great Artists to invite.
You can find the registration page on https://artcitadel.net/join-us/
Have a nice day!
