When you're out grocery shopping, especially at Walmart, always look at the travel section. Walmart offers overage (which means extra money towards your other purchases) and not all coupons have size restrictions.
Dial Body Wash travel size $0.97
Coupon for $2.00 (6/12/11 inserts)
which means FREE + $1.03 overage
This is a great deal, not only do you get overage you have a handy travel size body wash for travelling!
*Don't forget that your overage is applied to the other items you are purchasing. So this is great when buying items like milk, eggs, and bread because there are little or no coupons available for these types of items.
