In the Tumult store you buy the regular or full licensed application. This license allows full use, including commercial use, meaning you can earn money with the product you have developed with Hype.
The education store is for training and education facilities as well as for students (usually graphic design, web design, application development etc.). They can download a much discounted application for the sole purpose of learning different graphic design applications. The application is exactly the same, however, the license is different and will limit the user to learning and practicing (or even producing something for non-commercial purpose). The license usually does not allow commercial use. This justifies also the discounted price. To get a student teacher licensed application, someone may need to prove eligibility.
Hope this clarifies the issue a bit.
