The pack-size trapThe biggest pack we tracked (132 oz) looks like the bulk play, but it runs 45¢ per oz — the 7.3 oz pick wins at 8.8¢ per oz. Bigger isn't automatically cheaper.
Median across all 58 tracked listings: 30¢ per oz. The worst deal we saw ran $2.48 per oz — same product category, 28.1× the price per unit.

How we figure this out
Once a month we pull live Mac and Cheese listings from Amazon, Walmart and eBay, read the honest quantity out of each one (ozs, in this case — the unit that actually matters), and divide the real price by it. Coupons that change what you'd pay today are applied; "subscribe & save" teasers are not. Then everything gets ranked by cost per oz, because a big box with a small number inside is still a small number.
