Quantities are estimates for planning. Adjust for appetite, health needs, climate and what you already have. Food is sized at about 2,100 kcal per adult and 70% of that per child.
Prices are estimates for typical pack sizes, rounded up to whole packs, checked in late October 2026. They will drift; costco.com prices can differ from warehouse prices, and Amazon prices change often. Costco items marked "not usually stocked" are counted at Amazon in your picks.
Store links are plain searches on costco.com and amazon.com. No affiliate links, no tracking, and nothing you enter leaves your browser unless you send it.
