Tracking your mail is pretty easy if you use FedEx, UPS, or the postal service's priority mail. But what if you want to track your mail with more accuracy and send it however you want? Uh, OK. I guess there are legitimate reasons for that.
Simply stick in this GPS Mail Logger with your letter or package and you'll be able to follow it wherever it goes. Which is good, because this is one package you really don't want to get lost: this tracker costs a whopping $695.95 for some insane reason. If you feel comfortable mailing that thing out and trusting the recipient to return it, that's your call. Me, I'll just trust the postal service.
