A friend of mine decided to not use any illegal software on her computer on moral grounds and wanted CS5. When she started a Photoshop course the other week I helped here to get the student edition of CS5 from Adobe. Now the course she is doing is an Adult Education course 2 hours/week for 10 weeks cost £53.
She paid for the CS5 and then they ask for proof of the course and identity, so we scanned the enrolment form and her passport and sent that. We had to phone up because the Adobe user interface on their site wasn't very intuitive, only seemingly allowing one file to be sent, but anyway it got sorted. Received the CS5 3 days after payment.
The cost was £186 as compared to the full price of £644.
She was offered Lightroom 3 when buying CS5, again with the Student Discountm for again £186 I think.
The Adobe site says about who can qualify for the Student Discount, which as you can see above is considerable;
* attending a primary or secondary school, university, or college
* enrolled full- or part-time with a valid student ID
