Amazon is currently offering a free one-year subscription to Amazon Prime, which will give you free two-day shipping on most items that Amazon sells with the option to upgrade to one-day shipping for $3.99. The annual cost for Amazon Prime is $79, so this is a great deal that every student should take advantage of, even if you only shop at Amazon occasionally.
Undergraduate and graduate students qualify for the free subscription. To sign up, you’ll just need to do enter your .edu email address and choose your state, school, year, and major. I’m not sure how long they’re running this special, but if you’re a student, I’d recommend signing up soon.
