Editor's Notes & Price Research
Tile Mate easily loops onto keychains or attaches to anything you don't want to lose so you can find it fast. Compatible with Apple iOS and Android devices with Bluetooth 4.0. Contains a battery that is designed to last at least one year while giving you maximum performance. At the end of the year, you can renew your Tile with the reTile program.

I could not find any locally, but jcheng8999 on this thread suggested a price match to Target, and using that approach I was able to score a couple without the shipping wait.
It also looks like there's an option to get a 4 pack for $45.97.
Comparable price on Amazon is $24.97 for a single (low of $20.03 CamelCamelCamel), and $64.41 for the 4 pack so it looks like a reasonable deal.
Here's a review showing how this unit compares to the competition in the key finder space.
4 pack is also available locally for $45.97 (YMMV)
Pricematch at Target may also be an option.
BEWARE: some are reporting getting empty box for in store and online order. Seal is intact but empty inside.
