Amazon Prime Day in 2025 might extend to four days, a potential increase from its traditional two-day format, as Amazon reported to its sellers.

Amazon’s Big Spring Sale is the retail giant’s newest annual sale. It started in 2024 as a week-long sale with opportunities to save on outdoor items, cleaning products and other spring essentials. This year, the sale is back and it’s essentially a mini Prime Day, except the deals are available to all shoppers.

The Amazon Big Spring Sale comes to an end tonight. That means the Pixel 9 Pro, various OLED TVs, and most of Amazon's Alexa-powered devices will return to their full price by the end of the day. So if you've been on the fence about buying something, you only have a few hours left.
