Zhibit started back in 2005, even-though their websites look like it's still the nineties. Don't let the brutalist designs fool you, they're quite popular within the artist community, and their very friendly plans surely help: if you are convinced by the private forever free tier you can publish your site for $1/year (yes, that much).
For $5/month you get more space and higher res pictures. $9/month will give you your own domain name and more goodies.
All plans (including the $1/year one) will allow you to sell your art with zero commission, which is awesome.
Give Zhibit a try now, you may end up sticking with it for good.
