In order to get these free Nature Valley Granola Nut Clusters, all you have to do is text CLUSTER to 467467. You may notice that this is the number for ShopText, where you sign up for a free account and then simply text words directly to them in order to get freebies. Some Hiffers have reported that the signup process takes multiple text massages before you're fully in the system, so if you pay by the text, you might want to skip over this.
Something else you may want to skip over is late night Saturday TV. There's. Nothing. On. Trust me on this one.
