Prime Day, Amazon's biggest sale of the year, started at midnight on Tuesday (July 16) and runs until midnight local time on Wednesday night (July 17).

The mega-sale includes up to 60% off select Amazon devices and invite-only Amazon deals on Sony Headphones, Citizen Watch, LifePro, Peleton, SodaStream and Foreo.

Whether you're shopping for new headphones or another must-have item, Prime Day gives you the chance to save money. The only catch? Prime Day is for Prime Members only (click here to start your free 30-day trial). Prime members have exclusive access to Prime Day store deals, plus free shipping on millions of items.

This is one of the deepest Prime Day deals we've found on Sony headphones. The Bluetooth headphones feature Active Noise Cancellation and the battery lasts up to 50 hours at a time.

Prime Day features plenty of highlights on Fire TVs, Fire TV Stick ($17.99), Echo Show 8 ($60), and other Amazon devices, in addition to price cuts on top brands like Sony, Lego, Adidas, Dyson, Shark and more.

In addition to TVs, headphones, speakers, tablets and laptops, shoppers can save on Blu-ray, DVD and Prime Video channels, clothing, books, furniture, appliances, beauty products, office supplies, cleaning supplies, cookware, gardening supplies, pet supplies, gym supplies, luggage, sporting goods, outdoor gear, video games, toys, jewelry and more.

How to request an invitation

After selecting an invite-only offer from the Amazon offers page, go to the product details page and click “Request Invitation”. You will receive an email notification confirming your request, and if the request is accepted, you will receive another email (or mobile push notification).

If you are invited to participate in the deal, you will have until the end of Prime Day to purchase the product if your request is accepted, but you can also choose not to purchase.

Only one invite per item may be requested, but you may request invitations for multiple invite-only items. There are only a limited number of invitation-only promotional products available and not all invitation requests will be honored. Be sure to keep checking your email or notifications as invitations will be sent out during Prime Day.
