Prime Day 2019 is a two-day parade of epic deals, starting July 15 at 12am through July 16. Prime Day is an annual celebration with awesome deals and exciting product launches, plus live entertainment and more, exclusively for Prime members.

Amazon’s members-only summer anniversary sale, Prime Day, is just about the biggest online shopping event of the year after Black Friday. This year, the 48-hour sale will last from 2:59 a.m. Eastern Time on Monday morning, July 15 (midnight Pacific) and run through Tuesday, July 16. In previous years, the sale has only lasted 36 hours, so you’ll get some extra shopping time this year.

Outside the U.S.? No problem. Prime Day deals are available in 18 different countries, including the UK, Canada, India, Germany, France, Australia, and more.

Limited-time flash sales can be stressful, and you want to be prepared to grab those amazing deals before they’re gone, so here are five ways to prepare to have the best Prime Day yet.

Sign up for Prime (obviously).

As the name suggests, Prime Day deals are only for Amazon Prime members. If you don’t have a membership yet, sign up for a free trial now—the promotional period lasts 30 days. After that, Prime costs $13 a month or $119 a year. If you’re considering whether or not to make the jump to a full Prime membership, check out our list of all the perks Prime gets you beyond just free 2-day shipping.

Start thinking about what you want to buy on Prime Day.

Amazon devices are certain to go on sale, so Prime Day would probably be a great time to grab a Kindle e-reader, Fire tablet, Ring doorbell, Fire TV Stick or Cube, or an Echo. Bookmark this page to see all the Amazon device deals next week. What kind of discounts should you expect? Last year, Kindle Paperwhites were discounted $40 for Prime Day (going for $80), while Fire HD 10 tablets were listed for $100, a $50 discount. Prime Day is also often a good day for books: Last year, Amazon offered customers credits toward a future book purchase when they bought Amazon Charts books or Kindle e-books, as well as discounts on Kindle Unlimited subscriptions.

Other things that have gone on sale in previous years: Instant Pots, 4K TVs, luggage sets, Blu-rays, smartphones, FitBits, robot vacuums, and more. There’s a higher likelihood that last year’s models will go on sale rather than the latest and greatest gadgets, so if there’s anything you coveted for Black Friday in 2018 that you didn’t end up buying, Prime Day might be your lucky day.

Check out the pre-sale deals you can already get.

Amazon is already offering a bunch of Prime-only deals in the lead up to Prime Day next week, including discounted Audible subscriptions ($120 per year, with an Echo Dot thrown in for just $1), discounted Marvel movie rentals ($2 each), 25 percent off Pepsi-owned brands like Lay’s and Gatorade, and more.

You can already save on products sold by Woot, like this Wi-Fi-enabled countertop garden kit ($140 off right now), Stone and Beam home goods (including cookware sets, furniture, and decor for up to 20 percent off), and various Amazon-branded household goods, like coffee pods, toilet paper, trash bags, pain relief medication, and laundry essentials (all 20 to 25 percent off).
