When you set up a subscription order we will deliver products you want at the interval you select for delivery. There is a 10% discount on every subscription order placed so you will pay the product price at the time of order less your 10% discount. You can be assured that any time a subscription order goes through you will be getting it for a discounted price to the active retail price at that time.
