Amazon has been running some pretty fantastic daily Prime Day countdown deals for the past week, and we've shown you all of the best offers each and every day. As impressive as those bargains have been though, they're nothing compared to what's coming tomorrow, July 12, when Amazon officially kicks off its second annual Prime Day shopping event.

Remember how impressive the sales were on Amazon for Black Friday this past holiday season? Well that's nothing compared to what's in store for shoppers tomorrow. Trust us, you're going to want to get in on the action when Prime Day kicks off at midnight Pacific Time on Tuesday, and we'll tell you everything you need to know about this crazy shopping event right here in this post.

In a nutshell, there are really only three things you need to know... when, what and how.

When: Prime Day officially begins at midnight Pacific Time on Tuesday, July 12. That's tomorrow, so you had better be ready.

What: Amazon will offer more than 100,000 deals across all departments and product categories, and these deals will be available in 10 different countries. That's a whole lot of bargains, and it's the biggest shopping event Amazon has ever had. That's right, there will be even more sales tomorrow than there were on Black Friday last year. Crazy!

How: This is the important part, bargain hunters. There are two different elements in our brief "how" section.

First of all, you need to know where to find all the best deals. After all, there are going to be more than 100,000 bargains available in tomorrow's big Prime Day sale. Do you want to look through more than 100,000 products? Now, of course you don't. Instead, follow along in our Prime Day 2016 hub, where we'll highlight all of the best Prime Day sales on the hottest items.

You can also subscribe to the RSS feed from our Prime Day hub if you want, or you can follow the BGR Deals account on Twitter to catch all the best deals.

Last but most certainly not least, you have to be an Amazon Prime subscriber to take advantage of any of the Prime Day sales. Prime gives you unlimited free two-day shipping on eligible items on Amazon's website, and you also get access to things like Amazon Video, Amazon Music, cloud storage and plenty more. The cost? $10.99 per month or $99 per year.

But guess what -- if you're not already an Amazon Prime subscriber and you want to get in on all the action for Prime Day, you can do so without paying a single cent. Simply visit this page on Amazon's website and you'll be able to sign up for a free 30-day trial of Amazon Prime. If for whatever reason you decide Prime service isn't for you, you can always cancel after Prime Day is over and you'll never have to pay a dime for Prime.
