Website & Shop Options
Having a website is always recommended! It's a great way to link to your social media, have a gallery for con applications, and list your commission information.
Be sure to buy a domain name first ASAP!
Website-Only Platforms
Note that some shop platforms listed in the next section also include the option to add on pages to make a full website!
Free Options:
https://wordpress.com/ (more restricted than self-hosted WordPress below)
https://sites.google.com (this site is made using Google sites!)
Paid Options:
https://wordpress.org/ (free, but you need to pay for your own hosting)
Dealer/Artist WordPress theme: https://shop.deguweb.dev
Hosting Suggestions: https://www.hostkoala.com/, https://www.a2hosting.com/

List of recommended apps
Note there is also the Shopify Starter plan which is only $5 a month. It has less options, but still a working online store! Shopify Starter plugin for WordPress: https://shop.deguweb.dev
There are other options listed in the spreadsheet above that I don't particularly recommend.
Print-on-Demand: Don't want to deal with packing and shipping? Free to list your items, fees or payouts only when you make a sale.
