For a low $7/month you can sell on Artfire. Yea they have a free store but you can only list 10 items at a time. Now there's Etsy which charges $0.20/listing and then a 3.5% commission once an item sells. For $7/month I can have unlimited listings, for right now I have 30 listings so were I on Etsy that would be $6 right there not including commission of course. I'm in the process of making about 10 or so other things so that would be another $2 right there, I already made up my $7/month for this month.
