Amazon is running a one-day-only promotion on its 8.9-inch Kindle Fire HD tablet, offering $50 off the $299 price tag. While it's not the best tablet around — we definitely recommend paying the extra $15 to remove the ads from the device — the Fire HD got a generally-positive 7.9 in our review. The Kindle Team tweeted that "quantities are limited," so if you're interested head on over to the source link below and use the code FIREHD89.
