Walmart and Verizon are selling the Apple AirTag 4-pack on sale for $79.99.
Walmart.com for $79.99 (affiliate link), stack with Chase Offer for additional 5% back
Verizon.com for $79.99 – use Chase INK Cash for 5x points
I’d be surprised if Amazon.com doesn’t match this price too, currently it’s at $89.99 on Amazon (affiliate link)
You can try going through a shopping portal for additional savings. A lot of people find AirTags useful for tracking luggage and a host of other uses.
