Losing keys and wallets is a source of stress that tracking devices solve by locating the exact position through your phone. Individual (Apple) AirTags sell for $29 apiece which puts two units at around $60 before you add in Apple's usual premium. Amazon's deal for Black Friday flips this math on its head by offering a four-pack for $64, down from the regular $99 price. You're basically paying for two AirTags at full price and getting two additional units as bonus freebies.
Apple's AirTags have become one of my essentials while traveling, namely because they let me check whether my luggage is in the right place instead of panicking at the baggage claim. And right now, you can get a four-pack of AirTags at Amazon and Walmart for $64.99 ($35 off), which is just a few cents short of the bundle's all-time low. The sleek Bluetooth trackers let you check their location using Apple's Find My app.
