Amazon Prime Day 2024: Best deals on health and fitness gear and science kit

Amazon Prime Day is July 16/17 this year, and there are some great deals on fitness and science essentials like air purifiers, running watches, treadmills, electric toothbrushes, telescopes, microscopes, binoculars and more. We’re already starting to see prices slashed on some of our favorite brands, like Garmin, Fitbit, Apple, Celestron, AmScope and Sony.

Or, if you’re considering investing in a new bit of kit, we’ve written up some guides, for instance: Should you buy a Garmin this Prime Day or should you buy an air purifier. We’ve weighed up the pros and cons of buying now vs risking waiting for a later sales event for a potentially better deal.

What is Amazon Prime Day?

What is Amazon Prime Day?

Amazon Prime Day is an annual event that happens in July each year. During the event, Prime members can access special deals on a range of products — but a lot of items are on sale for the general public, too. Sign up for Amazon Prime.

Who else has a sale during Amazon Prime Day?

Sometimes big retailers like Walmart and Best Buy compete with Amazon during sales events — this isn’t a guarantee though and as this event is a ‘surprise’ sale there may be fewer retailers offering deals. If you’re looking for particular products at low prices, have a scroll through our round-ups of the best treadmill deals or electric toothbrush deals.
