If you drop 25% of the purchase price for either the $229, 7-inch Kindle Fire HDX or the $379 8.9-inch option, you can get your new tablet right now while paying the remaining cost in three, 90-day installments. That's about $95 up-front for the larger tablet.
Although Amazon won't charge any interest for the deal, AllThingsD did spot one interesting clause in the fine print. If you fail to pay your installments, the company can "deregister your Kindle Fire HDX device, which will block your ability to access Amazon content."
Basically, Amazon disable much of the tablet's functionality until you pay up.
Alongside the incremental payments, Amazon is also launching a sale of Kindle accessories. Starting today through December 23, it's offering 30% off personalized Kindle covers and skins.
