We apologize if the announcement caused any confusion. For the next 90 days these plans can be added to any H or Breeze purchased after 8/8/2016. Plans purchased for any product that was purchased prior to the announcement will start on the day pf purchase. After 11/8/2017 plans must be purchased within 90 days of your drone purchase. These plans will have a start date that matches the drone purchase date.
If both plans are purchased you can use both discounts. Only one at a time can be applied to a drone purchase. You could receive 20% off one drone purchase and 30% off another.
Hope this helps clear things up
