Unless you’ve been living under a rock, you probably know that Amazon (AMZN) Prime Day will happen Tuesday July 11.

The third annual sale by the e-commerce giant will feature thousands of lightning deals only available to Prime members – they will be in limited quantities and available for a limited time. From kitchenware to electronics, the inventory is diverse, and you’re guaranteed to find something you didn’t even know you wanted.

If you’re a Prime Day newbie, here are some things to know.

When is it?

Prime Day is July 11, but some deals will become available as early as 9pm ET on July 10. New deals will start about every 5 minutes for 30 full hours.

Certain deals that are labeled “Spotlight,” may return on July 11 while supplies last.

Not a Prime member?

You have to be a Prime member in order to take full advantage of the deals, but it’s not too late. Simply go to Amazon.com to sign up. New members get a 30-day trial membership for free, so you could basically sign up for Prime Day, take advantage of the deals, and then cancel your account. If you want to keep it, membership costs $99 for the year, and includes free two-hour, same-day or two-day delivery. Students can sign up for a free 6-month trial here.

How to find deals

Own an Amazon voice activated device like an Echo? Simply ask “Alexa, what are your deals?” The voice-activated personal assistant will share exclusive deals for shoppers and even buy them for you. (Synergy!) The deals are available on the Amazon Echo, Echo Dot, Echo Show, Amazon Tap, Amazon Fire TV, Amazon Dash Wand, and compatible Fire tablets.

On the Amazon app or website, go to Today’s Deals and then click Upcoming. There you can see all of the deals 24 hours before they are live. If you’re using the app, add items that you like to your watch list and get an alert when it’s available to buy.
