Amazon Prime Day is a summer sale that was first introduced in 2015. At its start, Prime Day was a single-day event meant to celebrate the company’s 20th anniversary. Over the years, it’s expanded into a 48-hour event, but this year it’s getting another extension: Amazon Prime Day 2025 will be four days long.

Though Amazon Prime Day doesn't officially kick off until July 8, you can shop big savings already on brands like Apple, Dyson, Shark and more.

Prime Day 2025 is nearly here, and Amazon is bumping up the number of shopping days to score deals. Here's what we know about the sale.
