Amazon may already be selling its Kindle range at cost, but here's your chance to snag one for even less. The e-tailer's knocking a cool 50 bucks off the 8.9-inch Kindle Fire HD just for today -- valid on both the WiFi-only and the 4G LTE editions. Just use the code FIREHD89 while checking out and you can save enough to get rid of those pesky ads, load it up with apps, and still have some left over for a few literary classics.
