Not many people know that grocery manufacturer coupons can be used for a variety of products the same manufacturer has.
You don’t need to use the coupon on the exact brand. You only need to use it on something from the same manufacturer or “family.” Obviously, it isn’t broadcasted to the consumer that this can be done, but it always works.
For example, if Kellogg’s puts out coupons for Kellogg’s Special k, you can actually use the coupon to buy any type of cereals by Kellogg’s, even if the coupon doesn’t say it.
