Domestika has extended their Black Friday Cyber Monday sales to Dec 8, 2020.

Check out the art courses on their website, many going at just US $9.90.

To save even more money, see their course bundles which has discounts on top of the Cyber Monday listed prices. I bought a few courses at an average of US $8 each.

Note the languages before you buy because some are not in English, but do come with English subtitles.
