Inexpensive bulk granola

We eat enough granola that we can’t keep up making our own. But most store-bought granola is way too sweet with sugar. And it’s expensive. For the past many years I’ve been gobbling up Bob’s Red Mill Honey Granola. It is only mildly sweetened using honey, and not expensive. Amazon sells it in 18-ounce packages. We add our own nuts, raisins, etc. — KK
