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.

What's the price for feeling more secure in your home? How does a hundred bucks sound? That's the Amazon Prime Day price of the Ring Floodlight Cam. It's marked down from to $100 (from $180), so it's a significant savings, especially for a top-of-the-line security system.

Smartwatches aren’t for everyone. Maybe you don’t want to wear a screen-equipped gadget to bed, or you’re just after something that’s less obtrusive. Subtlety is where smart rings like the Oura Ring 4 shine, and Prime Day has knocked down its cost. It costs $296.65 ($52.35) from Amazon, which is both its best price and first significant discount.
