It looks like one person has already discovered this, but the Affinity Publisher courses are now available on Udemy. That means sometimes the better deal will be there when the courses are part of a promotion and sometimes the better deal will be on Teachable if you use the discount code MLH50.
They’re each about two hours long and mostly project-based except for the non-fiction one.
With the release of these courses to Udemy that means for each of the below topics you have an ebook, black and white print, color print, or video option to choose from. Description and links below each image.
