Note: It does not ask for the reason you were dissatisfied as far as I can see on the link nor is there an official form. Align is a probiotic supplement that helps with digestion. In other words, if the good bacteria in your digestive track were killed by an antibiotic, this restores the balance. There were two Align $3/1 or $7/2
coupons in the P&G 3/7 insert

Here's a funky guarantee on Head & Shoulders. Your hair will look thicker in one week compared to unwashed hair (??!!) or your money back. Mail unused product and original cash register receipt for up to $12.99 including s&h. Limit one refund per name, address, household. Valid one year from date of purchase. Return the unused portion with the dated cash register receipt. Print your name and address on the back of the receipt along with the reason you were not satisfied. Send to:

Head & Shoulder Guarantee,
Box 900244
El Paso, TX 88590-0244This guarantee was seen in the March P&G insert next to the $1 coupon for Head & Shoulders. When you call the number 1-800-843-3543 you can hear the details of the ‘thicker than unwashed hair’ guarantee.

As I mentioned before, my thoughts on sending back the unused portion is that I would use most of the bottle before making a decision to send it back. That gives you a fair chance to decide if you like it or not, and if you decide to send it back, it's cheaper on postage.
