The cheapest legal way is to qualify for the Student version. I paid £150 for an Open University course and I've saved over £1000 in student/educational software.
can you enrol on any ou course to enable you to get software student discounts. For example this course only costs £120.

Would Adobe accept this to get a student discount?
For OU courses, what ID do you send as proof?
Do teachers qualify for this discount?
