Get an Apple AirTag for less than $20 each when you buy 4

Apple product discounts don’t come around all that often, so when they do, it’s worth checking. Best Buy’s 48-hour flash sale is offering a great deal on the famous Apple AirTags . So the next time you lose your wallet, keys, or whatever, you don’t have to panic. These little tags can be attached to all your important items and use Bluetooth and ultra-wideband technology to help you track them down if you lose them.

For a limited time only, you can get the four-pack for only $76 at Best Buy. Apple’s four-pack of AirTags normally retails for $99, so you’ll save $23 with this deal. Note that this offer ends on Sunday, August 4, so if this interests you, do it now before the offer expires.

AirTags are one of our favorite item trackers and they work seamlessly with your iPhone and the Find My app with a simple one-tap pairing process. You can then throw a tracker in your pocket as is or a AirTag Accessory to attach them to your keys, hang them on your bag, stick them on your bike or anything else you want to keep an eye on.

Once set up, your AirTags will appear in the Find My app, displaying your items on a map so you can easily find them. If an item is near you, you can use the app to play a sound through the AirTag’s small speaker to help you find it, and use the Precision Finding feature to be guided to your missing possession. This is useful if you’re just looking for your keys or wallet around the house, for example. If you lose an item further away, you can put it into Lost Mode, which will ping you when the AirTag is detected on the Find My network and allow you to add a message and provide your phone number or email address.
