Step 1: Have Prime.
Don't have Prime? ...what are you doing with your life? First off, you get free two-day shipping on EVERYTHING you buy using Prime. Luckily for you, if you don't have Prime, you can start your free 30-day trial here, meaning you can reap the benefits of Prime Day without fully committing to it. However, you'll certainly see the advantage of having Prime and get hitched to your new favorite online service.
