Never heard of Shaw's, I'm assuming it's a regional place.
But yeah, I see what you mean, it does seem like it's the big box stores that have the better selection of cereals, especially specialties. I remember back in the waning days of the glorious Oreo O's, Walmart was the only place that still had them for a while after they stopped making them; and likewise, anytime Berry-Berry Kix made a triumphant return, undoubtly it was Walmart where you'd find it.
