NapperC Unfortunately, there is no discount, but we do offer the Education License, which can be purchased by educational institutions. If it is for learning purposes, you may ask your school to purchase the Spine Education license.
If you plan to use Spine to create products for sale, you will need to purchase your own license, as the Education license is not available for commercial use.
We recommend that you purchase the Essential license first. Although the advanced features such as meshes and constraints are not available, you can still create a wide variety of animations. For example, all of the animations described in the following article can be created with Spine ESS:

You can upgrade from Spine Essential to Spine Professional at any time for the difference in price. Projects created in Spine ESS can also be opened in Spine PRO, so you can continue to enhance projects created in ESS after the upgrade.
