Update 11:45 a.m. EDT June 29: Prime Day will officially take place on July 11, and it will be 30 hours long, beginning at 9 p.m. EDT on Monday, July 10, Amazon announced Thursday.

Original Story:

Once a year in mid July, Amazon bestows it’s valued Prime members with an extra perk, Amazon Prime Day. It’s the day when a number of items on Amazon are available at fractions of their usual prices. Everything from the Kindle Fire to beauty products see massive price drops, and users snatch them all up in a frenzy.

The deals are great, especially if you’ve been waiting to make a big purchase and can’t hold out until Black Friday or Cyber Monday roll around in November. Amazon hasn’t released the details of all the best deals yet, nor has it announced the exact day it will all take place. A page that says Prime Day 2016 has ended also says, “Prime Day is a one-day-only global shopping event exclusively for Prime members. With thousands of amazing deals worldwide, members get exclusive access to the biggest discounts on things they need, things they want and everything in between — across nearly every product category. There’s something for everyone!”

In the past, Amazon Prime Day has been held during the second week of July. Last year it was on the second Tuesday of the month, the year before that, it was the second Wednesday. Guesses for this year’s date are mostly falling on July 11, the second Tuesday. International Business Times reached out to Amazon about the official date but Amazon did not respond.

Fortune reported some Amazon sellers are not only predicting the July 11 sale date, but also are guessing the “day” actually will last 30 hours. Other sellers are guessing there will be a “Prime Week,” featuring different deals each day.

How to get Amazon Prime Day deals?

Amazon Prime Day is exclusively for Prime membership holders. The membership costs $99 for a year of Prime services including free two-day shipping for Prime items, free music and video streaming, same-day delivery in certain areas and more. Alternatively users can pay by the month, which costs $10.99/month. Students are eligible for free six-month trials when they sign up for the service with a student email address. And anyone can start a free 30-day trial anytime they want. So if you haven’t used your free trial before, you can use it for Prime Day. If you sign up for the free trial, just write yourself a reminder to cancel it before your 30 days are up — unless you want to start paying for it.  

What deals happen on Amazon Prime Day?

Last year for Prime Day, Amazon dropped the price on most of its original products. The Kindle Fire, Amazon Echo, Fire TV and other products all saw dramatic price drops. The Kindle Fire was available for just $33, down from the usual $50. Other Kindles and the Fire TV were available with $30 discounts. The Amazon Echo was available for $50 less than its usual price. Products that aren’t Amazon exclusives also saw huge discounts. The Toshiba Chromebook 2 was available at a $120 discount for just $279 and other items available through toy brands were available at 50 percent off while active footwear saw 60 percent slashes in prices. 

Amazon hasn’t released a list of deals for this year, but if they’re anything like last year, Prime members are in for some major savings.
