There is a great printable out there for $1.60 off Nature Valley Granola Nut Clusters, this coupon was available last month. The great news is, even if you have already rinted it, you can print it again, as it has reset. Be sure to print this one quickly if you want it, they went quickly last time!
I have seen these on sale at the store for anywhere between $2.00-$2.50. so they would be really cheap with a coupon.
