Looking to treat yourself or a loved one to a new tablet this Christmas? As long as you don’t mind investing in Amazon’s ecosystem, you can currently find some incredible deals on the company’s third-generation Kindle Fire HDX lineup. For today only, a number of 7-inch 4G LTE models have at least half off.

That means you can get a Kindle Fire HDX 7 with 16GB of storage and Amazon’s Special Offers for just $139 — 50% off its regular price. You can get the same device without Special Offers for $147 — also 50% — and if you need more storage, you can get a 64GB model with Special Offers for just $159, which is 53% off its regular price.

These are all third-generation Kindle Fire HDX tablets, which were originally released last year. But don’t let their age put you off; these babies are packing sharp 1920×1200 displays with 323 pixels-per-inch, quad-core processors clocked at 2.2GHz, 2GB of RAM, and Adreno 330 GPUs. And because they’re Amazon devices, they all have a Mayday button for on-demand customer support all day, every day.

If you’re new to Amazon’s Kindle devices, there’s one thing to keep in mind: These run Amazon’s own version of Android, which does not support Google apps — including the Play Store. Instead, they have Amazon’s own Appstore, which is now home to more than 100,000 apps and games, and offers a free paid app every single day.

If you’re a Prime member, you’ll also get access to Instant Video and Prime Music, and free two-day shipping.

These reductions are good for today (December 8), and only while stocks last. If you don’t pick one up soon, then, you could miss out.
