The current 7-inch Kindle Fire HD.

The 7-inch Kindle Fire HD is regularly $199, but if you’re an AMEX cardholder, you can take American Express up on a deal through Twitter that’ll save you $50. It’ll bring the price down to $149, and you’ll get free 2-day shipping.

All you have to do is visit this page and follow the instructions. You’ll need to tweet one hashtag, wait for a response from the AMEX Twitter account, and then tweet the confirmation hashtag the account provides you with. After that, you can confirm your purchase and be two days away from your new Kindle Fire HD.

You’ll need to redeem this deal before March 3, 2013.
