Amazon is currently discounting its entire lineup of Kindle Fire tablets by $20-$40. The discounts apply to everything from the humble 8GB Kindle Fire HD all the way to the 64GB LTE Kindle Fire HDX, so you've got plenty of options to choose from.

• Kindle Fire HD ($119) | Amazon | Normally $139
• Kindle Fire HDX ($199) | Amazon | Normally $229
• Kindle Fire HDX 8.9" ($339) | Amazon | Normally $379

Priced at an extremely competitive $699, Samsung's new 28" 4K monitor packs in two HDMI 1.4 ports, a Displayport, and audio out, all while leaving a very small footprint on your desk. It also has a "picture-in-picture" mode which allows you to plug in two computers and see both video feeds by dividing the screen in half. [Amazon]

Update: It looks like Amazon's stock might have run out, so if you see a price higher than $699, it's from a third party seller. Probably best to wait and see.

If you just downloaded the new Microsoft Office apps for iPad, you probably noticed that they require an Office 365 subscription to actually create or edit any documents. Instead of signing up for that $100 in-app purchase though, save yourself a bunch of money by buying a subscription on Amazon.

Various third party sellers usually offer Office 365 through Amazon for $70 or less, so this isn't necessarily a limited-time deal, but it's a good tip to remember given yesterday's news. Once you've received your code and activated your account, you'll be able to use Word, Excel, and Powerpoint on up to 5 PCs or Macs, 5 tablets, your smartphone, and online through a web browser.
