Amazon is encouraging shoppers to create a shopping list of items they are interested in. Should those items go on sale during the event, Prime members will be notified.
If you're feeling a bit guilty during your shopping spree, Amazon has something for that, too. The company will donate a percentage of the price of all eligible purchases to the charitable organization of your choice.
What will be on sale? According to Amazon, more than 100,000 items will be on sale during the event.
Televisions will be a popular buy as in the past, according to the company. "Prime Day will include amazing TV deals, with a variety of great brands including the all new Element 4K Ultra HD Smart LED TV - Amazon Fire TV Edition. Amazon is planning one of its largest total volume TV deals in history with a record level of inventory but once again, the TV deals will likely sell out."
You will also be able to find deals on unlocked phones from Alcatel, BLU, Moto and Nokia.
You can also get four months of Amazon's streaming music service for .99 cents.
The company is offering up to 40 percent off book titles with a Kindle Unlimited subscription. The subscription offers access to more than a million book titles. The books can be read on any smart device.
