The four-pack is down to $90, marking the first major discount on Apple’s new item trackers.

Prime Day has brought a number of Apple deals, but one of the most useful if you’re planning to travel over the July 4th weekend or later this summer is on the new AirTags. The four-pack has dropped to a new low of $90 ($9 off) at Amazon and Best Buy, bringing the price of each tracker down to about $22.50. It’s not a big deal, but it’s the first time we’ve seen Apple’s latest AirTags discounted this heavily since they launched earlier this year. If you need more trackers, Costco is offering a five-pack of AirTags for $99.99 to members, throwing in the fifth tracker at no extra cost.

If you own an iPhone, I’d recommend buying an AirTag over just about any other Bluetooth tracker available. Unlike rivals that simply show an item’s approximate location, AirTags can guide you directly to them using onscreen arrows, vibrations, and sounds. The original model already did an impressive job, but the latest version can more helpfully guide you up to 50 percent farther away thanks to an upgraded ultra-wideband chip. Apple has also increased the speaker volume by 50 percent, making it easier to hear an AirTag when it’s hidden in a closet or otherwise out of sight.

While some big specs have evolved, Apple hasn’t changed some of the tracker’s best qualities. It still runs on a replaceable CR2032 battery and carries the same IP67 water and dust resistance rating as its predecessor. Apple has also kept useful features like AirTag sharing, which lets up to five people track the same item. You can also still temporarily share a lost item’s location with participating airlines like United, Delta, and American Airlines to help recover misplaced luggage.
