Amazon takes 25% off a selection of Orbit gum via this clippable coupon. Even better, cut an extra 5% off and bag free shipping when you checkout via Subscribe & Save. Combined, that puts many items below what you could expect to pay at local grocery stores as well as bulk stores. A couple of best bets, with prices after both discounts: Be sure to cancel Subscribe & Save once your order ships to avoid being billed for subsequent shipments.
