The "Black Friday" of online shopping, Amazon Prime Day, kicks off Monday afternoon -- and here's everything you need to know to score the biggest deals.
Amazon Prime Day is more than just a "day" of savings, though -- it's actually a 36-hour event. Deals go live at 3 p.m. ET and run through midnight on Tuesday.
The best deals -- 20 percent off or more -- will also be in the form of "lightning deals," or products that go on sale for a limited time. If you've got your eye on something, you can use the Amazon app to scan for what items will soon go on a lightning sale.
Using the app, click into the menu section in the upper left corner and choose "Today’s Deals," then click the "Upcoming" tab. If you see one you like, click "Watch this Deal" to be notified when that specific sale goes live. Be sure to have your notifications turned to "on" in the settings section of the app, however, if you want to receive notifications.
