If you have a .EDU email address you can receive a free Amazon Prime membership through Amazon Student. Amazon Prime offers free two day shipping for most purchases. I’ve had it (paid full price for it last year) and Prime has definitely been worth it.
I just discovered this great deal for students and was pleased that Amazon gave me a full refund for my renewal of my Prime dues since I haven’t used the account yet since it renewed a few days ago. If you have a .EDU email account, check it out!
