Here is a good list of 10 places to host and sell your online courses.
Our favorite place to sell courses in 2018 and beyond? Podia.com. it’s beautiful, elegant, easy to customize, takes NO fees and has a 100% free trial as well. (Podia is like a combination of the best features of Patreon, combined with Teachable or Kajabi, just less expensive, better looking and easier to use)
