This is a sort of repeat from a year ago that's live for another 12 days, though last year's bundle was IMO quite a bit better, not to mention $5 less than this year's $30 price tag. The big draw -- the thing that makes it worthwhile [IMO], is Corel Painter 2020. Like last year, the version of Painter is the last one -- not current -- though Corel has been sending me offers to buy Painter 2020 for $100 [they want $150 upgrade for 2021].

CorelCAD 2019 is likewise the last version -- current is v. 2020 -- at a HUGE savings over Corel's $699 asking price. This makes the bundle a better deal than ever *IF* you're into CAD, but I don't think that many people are, and those that do use CAD software I think tend to already be set up with whatever their employer uses, If they use CAD software at home.

The CorelDRAW Graphics Suite 2020 would be great, but it's a 180 day subscription -- it goes for $236.55 per year [Yikes!]. [That's more than I pay for a 6-user license for Ofc 365 Plus Adobe Photoshop.] The suite does a lot, including 7 apps, and I've owned & used earlier [less expensive] versions, but as a vector graphics app it's mainly suited for print work, which isn't really all that common nowadays, at least compared to a decade ago.

The bundle include a lot of individual Brush Packs, which are collections of special brushes to use in Painter -- the Humble Bundle site errors saying that 2 brush packs are PaintShop Pro compatible.
At the bundle's cheaper $26.96 tier, and also included for $30, is PaintShop Pro Std. 2020, again an older version. [As part of last year's bundle it was then current, plus you got the more expensive Ultimate version.] It's a good to great app for photo editing, but I expect the 2021 Ult. version to go on sale in the not too distant future for around $30.

In this 2nd tier you also get ParticleShop, the same version as last year, and years before that as the files are all dated 2016 [Corel hasn't been continuing development on this.] ParticleShop works as a plug-in to other photo editing apps, letting you use the special Painter brushes. You get a few PaintShop Pro scripts -- go to the View menu to add the Script toolbar to use them -- and from the $1 tier you get AfterShot 3, which Corel has been trying to push as a Lightroom competitor for years now. It's been at version 3 for quite a while now, and Corel's been giving or almost giving it away bundled with their other apps. I don't think most people have heard of AfterShot, which speaks volumes about its popularity. There's much better out there, and then there's Lightroom.
