Already took advantage of the deal. Great bargain. Humble Bundle do have some great offers on now and then. Depending on your needs the book bundle are great. If you want to get away from Adobe then this bundle is a pretty good replacement for photoshop. I already had a few of these from previous humble bundle offers but it was worth getting for Painter 2019 for $25.
If you haven't used Humble bundle before, some of the cash goes to charity. You also have the slightly limited option to choose where the money goes option to. For this offer you get three sliders to balance how much money goes to charity, Corel and Humble bundle themselves. Just move the sliders about until it balances out to your taste. Pretty cool.
Here's what you get for $25

PaintShop Pro Ultimate 2020
AfterShot 3 for PaintShop Pro
PhotoMirage Express for PaintShop Pro
GRFX Studio for PaintShop Pro
ParticleShop
