Sam,
The subscription fee is 100.00 + 50.00 for the tracking + 150.00 for the unit - a 50.00 rebate. The subscription is a auto renewal which there are a lot of complaints.
Damn that is ridiculous, I didn't realize the tracking was an extra $50 on top of the $100 subscription. You can get the older unit on Amazon for $100:
