What is Prime Day?

Prime Day 2023
Amazon’s 10th Prime Day event starts July 16 at 12:01 a.m. PDT and runs through July 17.
Prime Day is a Prime member-exclusive shopping event. Members will get access to millions of great deals on brands like Clinique, Allbirds, and Kiehl’s. New deals will continue to drop as often as every five minutes during select periods throughout the event, so members can come back and shop often to find something they love. Invite-only deals are also back this year, which means Prime members can request an invitation to exclusive deals that are expected to sell out. Learn more about Prime Day.
