It came as a bundle, so if you buy the Wacom tablet you'll get the download code for the Corel program for free. ;)
The program alone is actually not that expensive, but won't do you any good without the tablet, since it simulates traditional brushes etc.
Here's the one I got: https://www.amazon.com/Wacom-digital-graphics-drawing-painting/dp/B010LHRFYU. Only paid 50 $ since it was second hand. ;)
