Amazon.com has a cool promotion going – sign up for Amazon Student and get a free year of Amazon Prime (and they reserve the right to possibly extend that). For those not in the know, Amazon Prime is a $79 a year service that entitles you to free second day shipping on anything that’s eligible for free super saver shipping (ie, pretty much everything Amazon sells); next day shipping costs $3.99 per item.
When I saw this posted on Lifehacker, I ignored it at first because I already have Amazon Prime; I got in on a free trial years ago and found it to be too useful to do without. Then a friend of mine who also has Prime added her student account and found that they canceled the remainder of her Prime subscription, refunded her for it, and signed her up for the free year. That got me moving; it turned out I was only a few months from renewal, so I got a year free and a $13 refund on my subscription. Woot!
