PetHug via Groupon offers its GPS-Enabled Pet Link Tag together with a 1-Year PetHub Silver Subscription for $14 with free shipping. That's $38 off and the best such deal we could find for such a tag. The tag features a unique URL and QR code which are linked to your PetHub account. The silver subscription includes shelter alerts and email notifications with a GPS map of your pet's location. Deal ends January 26.

Of note, also available is the GPS-Enabled Pet DTA Link Tag together with a 1-Year PetHub Gold Subcription for $23. That's $42 off and the best price we could find. The DTA link tag features the PetHub logo, while the gold subscription has the added services of a new collectible tag sent out annually, pet medical insurance, and optional coverage for additional pets.

Note that you'll need to cancel your subscription after a year; otherwise you'll be charged $39 for the silver service or $49 for the gold service.
