If you are using coupons, it is essential to be familiar with the store’s Coupon Policy. Sometimes you can get a cashier that will give you a hard time or refuse to accept some coupons for one reason or another. I suggest you read each one and it doesn’t hurt to keep a copy with your coupons. That way you can show the cashier what their policy is.
