Some devices have promotional service such as a home monitoring kit or cameras. Some purchases may be made for a future gift. As such, the clock on the service should begin UPON ACTIVATION and NOT upon order date.
Same for a black friday special price for CAM PLUS. Regardless of the size or number of cameras purchased, I wish the subscription would begin when the 1st activation takes place.
