Amazon cuts an extra $3 off select Head & Shoulders products via this clippable coupon. (Note that while this coupon states it applies to purchases of two or more, it applies to single items as well.) Plus, when you add select items to your cart via Subscribe & Save, you'll get an extra 5% off and bag free shipping. Combined, that puts many prices under what you could expect to pay at local stores.

Note that many items are part of Amazon's "Add-on program" and can only be purchased with an order of $25 or more. Also, two items require Prime Pantry shipping of $5.99.

For Subscribe & Save orders, be sure to cancel the subscription once your order ships to avoid being billed for subsequent shipments.
