Why bother going outside on Black Friday when you can shop at home in your pajamas on Amazon? The online retail giant is giving us a sneak peak at its Black Friday deals today.

Included in the sale are several great buys, such as the $35 Fire tablet, $348 55-inch Roku smart TV and $99 Jawbone Up3.

The deals won't be available all at once, instead the sales will start in waves beginning on Friday November 20 through Black Friday. You'll need to check the website often to keep on top of the sales or sign up for alerts through the Amazon mobile app (iOS, Android and Fire OS) to find out when the deal on a particular product you want goes live.

There are also 150 "Lightning Deals" that you'll only be able to shop from the Amazon app. Those will go live daily between 3pm PST and 11pm PST starting Thanksgiving day through Wednesday, December 9. Finally, Amazon will have 10 "Deals of the Day" that will drop at midnight on Thanksgiving, plus 10 more new deals at midnight on Black Friday.

As an added incentive to shop, Amazon is offering Prime members two-hour delivery in 20 select metro areas, including Manhattan, San Francisco, Los Angeles, Dallas and Chicago, on select Deals of the Day during this sale and through the rest of the holiday season.

Check out some of the gadget deals you'll be able to buy through the sales in the list below. Amazon's not revealing everything that will be on sale, so that's why some details are missing.
