Apple's four-pack of first-generation AirTags has dropped to $60, marking a solid discount from the regular $99 price tag. That works out to $15 per tracker, versus the standard $29 per unit when bought individually.

AirTags are small Bluetooth devices that attach to keys, wallets, bags, and other items you want to track. They integrate with Apple's Find My network, which lets you locate lost items through your iPhone, iPad, or Mac. The trackers work best for Apple users, though people with Android devices can still locate an AirTag if the owner shares a link.

The current sale represents a 39 percent discount on the multi-pack. If you own multiple Apple devices or want to protect several items, this price makes AirTags more affordable than buying them one at a time. First-generation AirTags function identically to the current models, so you lose nothing by going with the older version.

AirTags require a one-time purchase of a battery replacement every year or so, depending on usage. A replacement battery costs roughly $2 to $5. The devices themselves have no subscription fees or recurring costs.

This deal suits anyone who frequently loses items or wants backup tracking for important possessions. Parents often use multiple AirTags to monitor children's backpacks and devices. Business owners attach them to company equipment. The low price per unit at $15 removes a barrier to buying more than one or two.

The sale appears time-limited, so the $60 price won't last forever. Stock up now if you've considered AirTags but found the standard pricing steep. This is one of the better per-unit prices these trackers have hit this year.
