What's the cheapest cereal per ounce on Amazon right now?

How does Dealophant calculate price per ounce for cereal?
Total listing price is divided by the canonical ounce count extracted from the product title. cereal is best compared by weight (price per ounce). Pack count and serving count are misleading because manufacturers vary scoop and bag sizes between products. 1 lb = 16 oz, so a "1.5 lb" listing is 24 oz. Cross-unit listings (for example a serving-count tub mixed in with weight-based tubs) are shown separately under "Other formats" so the price-per-ounce ranking stays apples-to-apples.
Is bulk cereal actually cheaper per ounce?
Usually yes, but not always — Dealophant has seen single-pack cereal undercut bulk on a per-ounce basis when the smaller size is on sale or has a Subscribe & Save discount the bulk listing doesn't. That's why Dealophant always recomputes per-ounce price live rather than assuming bigger = cheaper.
What's the typical price range per ounce for cereal?
It varies by brand, format, and current promotions. To see the live range, sort the listings at https://dealophant.com/compare/cereal by Price Per Unit ascending — the cheapest and most expensive in-stock options are visible immediately. The "Best Value" badge marks the lowest price per ounce in the current result set.
