Apple loyalists, this one’s for you. At this point, you know how handy Apple’s AirTags are as a tiny yet must-have travel companion that helps keep track of all your must-haves. That said, right now they just got a 35% discount, dropping them to just $17 at Amazon and Walmart — their lowest price ever. That’s actually cheaper than buying a 4-pack, which amounts to $17.49 each. We have no idea how long this deal will last, but it’s a good discount and definitely worth grabbing if you prefer to stick within the Apple ecosystem for your trackers.

Here’s how they work: AirTags can ping their own location, so when you attach them to one of your belongings, you can track that item via Apple’s Find My app, which is available in the cloud and on Apple devices like iPhones, laptops, and more. Through Find My, you can even tell your AirTag to play a sound so it’s easier to find.

Each one is completely encrypted for privacy, and even when it’s far away, it can anonymously and secretly use a network of Apple devices to send its location back to you. When you move away from an item like your keys, it can even send you a notice.

In addition to being water- and dust-resistant, AirTags have a wildly simple setup, and you can assign each one a name to keep your most valuable belongings sorted. After my car was stolen a few years ago and the thieves ripped out its GPS system, I bought one to keep in the spare tire in my trunk as a backup — and found it so useful I bought another to place in checked luggage (you never know where your bag might end up!). I haven’t lost my car in a crowded parking lot since.

AirTags have so many five-star reviews on Amazon, with an incredible 4.7-star rating. “The durability is outstanding,” wrote one reviewer, who added, “With their simple setup, tracking precision, durability, elegant design, and intelligent features, they are an investment worth every penny. If you’re an Apple user who values the security of your belongings, AirTags are an unbeatable choice. I’m extremely satisfied with my purchase and can’t recommend them enough.”

Join the hordes of others taking advantage of a rare Apple sale and grab a pack of four for the whole family or multiple valuable items.

And don’t forget about the lightweight AirTag holder options that are on sale that’ll make travel even easier.

A Belkin secure holder with a wire cable

Shopping editor Marquaysa Battle has written about this high-quality, locking AirTag holder before, noting that “reviewers love it because you can enclose the AirTag inside it, loop it around and lock it closed on everything from luggage to purses to keychains and beyond. Several reviewers noted that out of all the AirTag holders on the market, the locking aspect of this one is so tight, you actually need a small tool to get it open or closed.”

“I use this holder to secure my Airtag inside of my luggage,” reviewer, Josh, noted. “The allen-head screw makes it hard to remove without the tool as a deterrent to theft by a shady TSA or airport employee. A must-have!”

Promising reviews: “I really like how nice these look and how well they show off the airtag. I did not expect them to be nearly as durable though! i have put these on my keys which get tossed around and also on my luggage and they show no sign of cracking or coming lose. They may be a bit pricier than other options but these really feel like the premium choice.” — Ame

“I’ve bought two of these and have never regretted it. These are the only cases I have bought and will buy for my AirTags. I don’t trust the ones you can pop in and out, having the locking screw system gives me the peace of mind my tags won’t go missing. Easy to use and durable. They have never accidentally come open and that’s what it’s designed to do.” — Amber

A lightweight Bluetooth tracker wallet holder

This handy wallet holder can hold a single Bluetooth tracker snugly in your wallet. It’s smaller than a traditional credit card and it’s flexible, making it a perfect fit for various wallet types.

Promising review: “I bought a different holder that proved to be too thick and rigid for my wallet. I can use that one with a different air tag for an alternate purpose. This one works better for my “back pocket” wallet. (So far, no problems with the air tag falling out).” — Ctexhowlin

A budget-friendly 4-pack of slim holders

Another great option for baggage, these fabric holders have a sticky pack that attaches to most flat surfaces and allows you to slide AirTags in and out easily. These could be great for people who don’t want their Tags to “live” in their luggage, but want the ability to track their luggage while they’re traveling. According to our price trackers, a 4-pack is usually $9.99, which is still a great price.
