While many of us are still recovering from New Year’s celebrations, Amazon is considerably clearer-headed: it wants us ready for the winter school term that’s about to start. Appropriately, it’s offering a surprisingly steep discount on the Kindle Fire HD 8.9 for students. Americans headed back to class can get $50 off the price of the larger tablet for the whole of January, regardless of the capacity or the presence of LTE. The catch, apart from needing a .edu email address for the Amazon Student program, is the requirement for an active Prime subscription — although that’s no great shakes when Amazon accepts both the free six-month offer and the $39 yearly student plan. At $249, the discounted Kindle Fire HD is tempting for anyone who can do their course shopping at the Kindle Store… or just wants a convenient distraction during mid-terms.
