A permanent home/hobby license for Desktop costs $387, as far as I can tell. It only allows 4 cores being used, and for more you need to buy Core Extensions.

They do make some attempts on their web site to steer you into the yearly subscription, or into buying a yearly support contract if you do buy a permanent license, so some folks might not realize the permanent licenses are still available without a support contract.

They also run regular sales on all their products. Pi day is coming up.
