With orders of $25 or more for Prime members, Amazon cuts $4 off select Pantene products when you clip the coupon on the product page. Plus, all orders qualify for free shipping. (Non-members can spend $35 or more to qualify.) That leaves several items as free after discount and the best price we've seen. Deal ends January 9. A couple of best bets after coupon and with comparisons to local prices:

• Pantene Pro-V Repair & Protect with Keratin 12.6-oz. Shampoo for free (low by $4)
• Pantene Pro-V Beautiful Lengths 12.6-oz. Shampoo for free (pictured, low by $4)

Note that these items are part of Amazon's add-on program and can only be purchased with an order of $25 or more.
