Amazon is making a sweet deal to any students who haven’t gone back to school yet but still have some holiday gift cash to burn. As long as you have an Amazon Student account, the Kindle Fire HD 8.9 is available to you at a $50 discount.The Kindle Fire line has had one goal from the beginning: to disrupt the tablet market. As PC manufacturers began to try their hands at tablets, and Apple sat at the top of the heap with hardware and pricing that defined the industry, tablets were expensive. Then the Kindle Fire came and offered much of the same tablet functionality for much less than any of Android and iOS tablets on the market. When Google countered with the $200 Nexus 7, Amazon responded with the Kindle Fire HD and continued to offer superior hardware for less than their competition. Amazon has tried a number of times to offer incentives for users to continue their Amazon Student subscription, with hardware discounts serving as the latest attempt.If you have an Amazon student account in good standing, you’ll be able to see the deal. If you have a .edu address and have never created an Amazon account, you have six free months of their service, which includes Amazon Prime shipping. If you have already taken advantage of this service and your six months have lapsed, you’ll be out $69 to get yourself another year of the service. If your account is active, you will see that every 8.9-inch Kindle Fire HD has been discounted $50, starting with the $299 model. This discount is set to expire at the end of January, and at any point during this month if you have an active student account you’ll be able to take advantage of the discount. Even if you go to create your account right now, the deal is available to you.This doesn’t apply to the 7-inch Kindle Fire HD, due mostly to the fact that the tablet is already sold as close to cost as possible. Amazon makes very little off of their hardware, but the combination of kickbacks from content sales and the operating system level advertising on the Kindle Fire HD helps balance that out. If you’re not a big fan of the software, you can always root the Kindle Fire HD and turn the tablet into a stock Android device.
