Amazon Prime is normally 79 bucks a year. For that, you get free two-day shipping on any eligible item without having a required minimum purchase. You can also upgrade to 1-day shipping for only 4 bucks an item.
This sounds great, but not enough that I am willing to fork over the 80 bucks to get it. Well, now I don't have to. Amazon is giving away free 1-year memberships to Amazon Prime to all college students currently enrolled in at least one course (this means waiting until fall semester for me...). In the fine print, it also mentions that this offer may be extended beyond the initial 1-year period. In addition to the free shipping, Amazon will also email out exclusive student-related discounts and promotions, though you can opt out of these emails at any time.
The idea of all this, of course, is to get more students buying things like textbooks from Amazon. Given that Amazon pretty much ALWAYS has the cheapest prices for new textbooks - I'm anal and prefer new to used - I generally always order through them anyway.
