If I were smarter I could get free GasX

If I were smarter I could figure out how to get free GasX with these coupons...

Through couponing, I won't have to buy the hubby or I deoderant through 2011 and possibly 2012, won't have to buy him body wash at all this year, and didn't have to buy Kleenex for about 18 months, starting in late 2009. Couponing is awesome for HBAs... for food, not so much - lots of carbs go free or cheap, but not so much with veggies and protein.

 Please share how you do it. I need to learn which coupon sites are legit online besides just clipping the coupons in the paper.
