I currently have two main stores. If you'd like to tip me, I also have a ko-fi!
Storenvy I run myself, has prints, stickers, bracelets, pins, and my comics. Overall probably cheaper but the prints are likely not as great quality. I get more profit from here though!
Redbubblehas a lot more variety of products, though I get much less profit.
Inprint has a smaller selection of my original art prints, where I get a larger profit margin.
