You'll find it in the health food section of your supermarket (particularly Kroger) if they have it where you are. It's made in Blaine, WA (just checked the label) so I don't know if it has national distribution. I did find Bob's Red Mill (Oregon company) meusli in a Kroger in Wilmington, so at least some west coast brands are there.
