target   There is a nice deal at Target when you buy select hair care and personal care items-  Buy 3 and get a $5 gift card. Pantene is include in the sale and it is an excellent deal. You can get products as low as $.33 after coupons and gift card!   Here is one idea for shampoo/conditioner:  
Buy (3) Pantene Shampoo or Conditioner $3.99 each Use (3) $1/1 Pantene Coupons or Use $5/3 Pantene Products, exp. 9/14/14 (P&G 08/31/14) [ETS; Limit 4] Final Price: $.66 per item
$1.00 off Pantene Shampoo, Conditioner or Styler
 
If you need stylers, those also start at $3.99 at my store. Use $2/1 Pantene Styler or Treatment Product, exp. 9/30/14 (P&G 08/31/14) [ETS; Limit 4] or Use $1/1 Pantene Coupons or Use $5/3 Pantene Products, exp. 9/14/14 (P&G 08/31/14) [ETS; Limit 4] Final Price: as low as $.33 each!
Please note you may find some variation at your local Target.
