Go to P&G BrandSAVER now to request your BOGO FREE Head & Shoulders and/or BOGO FREE Herbal Essences! Wal-mart in particular is having a sale on their Head & Shoulders shampoos and conditioners for $3.96 each (originally $5.68) until Thursday June 20, 2013. No sale on Herbal Essences at Wal-mart, but hold onto that coupon because they usually go on sale for around $3 as well (at Shopper's Drug Mart, Wal-mart, etc.).
Buy 1 bottle of Head & Shoulders at Wal-mart for $3.96, and get the second bottle free. That's $1.98 each bottle.
