For college students only, Amazon.com continues to offer a free1-year subscription to Amazon Prime, its 2-day shipping service. That's tied with our mention from three weeks ago as a savings of $79 and easily one of the best shipping discounts we've seen from Amazon.com. You must be currently enrolled and be able to provide a .edu email address during registration. With Prime, 1-day shipping upgrades are available starting at $3.99.
Note that Amazon's new free movie and TV streaming service is not available with this offer. To get free streaming, you must be a paying Amazon Prime customer ($79 per year).
