If you look at the advertisements for more than three stores, you will become overwhelmed and frustrated. In other words, it will be information overload. Also, a lot of stores will have the same types of products on sale; so you won't be missing a lot. In order to save the most, find out which stores double coupons and allow stacking coupons. Stores that allow coupon doubling will make all the difference in your savings. Even though a store may have slightly higher prices than a competitor, the overall total may be less depending on their coupon policy.
