Amazon is hosting its annual Prime Day event, but for 2025, it is 4 days long (rather than 2). We're rounding up all of the best deals of the event so far and updating this article live with the cream of the crop.

In honor of Prime Day, Amazon is going against the norm with the first-ever price cut on Oura Ring 4: With a 15% reduction on all sizes, you can now buy the Oura Ring 4 in silver, size 10, for $297 from $349. Other sizes are also on sale, but some of them are already sold out.

The Oura Ring 4 is our choice as the best smart ring, and its Brushed Silver variant is on sale for the first time during Amazon's Prime Day at 15% off.

If a smart watch just isn't the right fit for you, you can check out the Oura Ring in its latest iteration. And get it on sale for Prime Day.

Prime Day is the idea time for a smart home upgrade, and the Ring Battery Doorbell Plus is almost half-price in this deal.

Prime Day is almost here with big savings on wearables. Find discounts on smartwatches, trackers, and earbuds to upgrade your fitness and daily routine early.

The figures apply across all online retailers for Amazon Prime Days. Tariffs and economic uncertainty are on the minds of shoppers as they prepare for Amazon's summer Prime Day sales. But at least one company is forecasting that sales for the online sales event will break records as budget-conscious shoppers look for deals.
