With orders of $25 or more, Amazon takes $3 off select Vidal Sassoon hair products when you clip the coupon on the product page. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise it starts around $5.) A couple best bets, with prices after coupon: Note: These items are part of Amazon's "Add-on program" and can only be purchased with an order of $25 or more.
