Many of my friends know that I love to save money and using coupons is one way I do. I try to follow the rules when using coupons and it frustrates me when stores don't make up their own rules or don't even know their policies.
So I made a list of websites where you can see and print the coupon policy for different stores. Print a copy of each policy and carry it with you so when you run into problems you can show it to the cashier. These are the only stores that I know that have a coupon policy. If you have any other links please add them in the comment section and I will update this list.
