Amazon just redid their terms and conditions to crack down on fake EDU email addresses for student accounts and to not implement a better policy. Anyone who signs up now recieves a free membership AND a referral credit ($10) in the hopes that more and more people will follow referral links and also provide them.
I followed this link:
I immediately recieved my free account and about a week later recieved an email with a code for my credit.
Please note: Must provide VALID edu email address
No referral links.
