Amazon Subscribe & Save
From diapers to detergent, dog food to deodorant, Amazon's Subscribe & Save can save you money and effort by sending you regular shipments of the things you use month in and month out. Amazon is happy to offer you a discount on products you want shipped to your home on regular schedule -- from once a month to once every six months. The discounts start at 5 percent, but you can bump that number up to 15 percent if you add five or more products to your regular Subscribe & Save delivery. You don't need to be a Prime member to use Subscribe & Save, but the savings are a little sweeter for Prime members -- a 20 percent discount on some products.
