Staples [staples.com] has Apple AirTag Tracker, 4/Pack for $69 as shown in weekly ad [staples.com].
The $69 price is valid in store only so YMMV.
You may be able to check for availability (by choosing the "1-Hour Pick Up" Option on website) before going to your local Staples store. If it's not on the shelves, you can try asking an employee if they have any in the back.
