How we priced this
Every row is the largest standard box of Size 4 (the size most families buy the most of), at the regular shelf price — not sale, not subscription. Prices were checked on retailer sites on Oct 4, 2026. Rows marked price not directly verified come from third-party listings or were blocked by the retailer's bot check; treat those as approximate. Costco's Kirkland price is members-only.
