Prices on Amazon often change quickly. You need to be logged in to clip coupons, which are limit one per account and will come off just the first shipment. You can cancel subscribe & save or skip a shipment at any time. You get 5% off and free shipping with subscribe & save, which increases to 15% off if you have five subscriptions on the same day/month, or (through 11/11!) 20% off if you have five + Amazon Mom with Prime.
