The Amazon Kindle Fire HDX 8.9 is now available at a 30 percent discount, but the offer is only good for today, Dec. 22.

As part of a new Amazon Gold Box Deal of the Day promotion, all models of the Kindle Fire HDX 8.9 are now available for 30 percent off their regular price tags, just in time for the holidays. Coincidentally (or not?), the deal is valid only on Monday, Dec. 22, which is also the last day can choose two-day shipping for their orders and get the package in time for Christmas.

If you take into account all storage configurations, connectivity options, and the models with or without advertising, you can choose from 12 different variants of the Kindle Fire HDX 8.9. As previously mentioned, Amazon has slashed the price tags of all available models, so here's a quick rundown of what's in store:
