We can't besure that prices won't change over time (whilst we don't have plans to change it on this product). However in the rare case that a price does change, a reminder email with the price is sent to all customers with reoccurring orders a couple of weeks before the reoccurring order is due to be sent. At this time you can cancel if you wish.
