Subscribe and save. With the “Subscribe & Save” option on Amazon, Prime members can save up to 15 percent on products they regularly buy. In addition to extra savings, the option also ensures that you don’t run out of necessities like diapers and laundry detergent. All eligible subscription products are reduced by 5 percent, but if you subscribe to five or more products, the discount increases to 15 percent. The discounts don't have to stop there. Be sure to do some digging because there are often extra coupons that can be applied as well. It's also worth mentioning that you can skip, cancel, or change delivery dates at any time. Shop all Subscribe & Save eligible items here and receive an extra 20 percent on your first delivery.
