Amazon offers the Cascadian Farm Organic Cereal 9.2-oz. Box in Cinnamon Crunch for $3. Clip the 20% off coupon on the product page to drop it to $2.40. Prime members qualify for free shipping. (Non-members can spend over $35 for free shipping; otherwise, it adds $7.05.) That's the lowest total price we could find by $6. It's also a buck less than what you'd pay at a local store.
