Costco organic shopping list for a family of four

This page mirrors your **Main List** on Costco same-day (Instacart): **93 saved products** imported 2026-11-01, plus **organic kiwi** when Costco stocks it (94 product pages on this site). For a family of four we tag each line as **weekly basket**, **stock up about every month**, **every 2 months**, or **every 3 months** — see the homepage for an **average monthly spend** amortized across those cadences.

  • [Weekly basket](/categories/costco-organic-weekly-family-four/)
  • [Stock up ~1 month](/categories/costco-organic-stock-1mo-family-four/)
  • [Stock up ~2 months](/categories/costco-organic-stock-2mo-family-four/)
  • [Stock up ~3 months](/categories/costco-organic-stock-3mo-family-four/)
  • [Every Main List product page](/collections/affordable-organic-grocery-stores/) — titles, pack sizes, same-day links, and observed prices

Cadence tags are our family-of-four suggestion; move items between lists anytime as your household eats through warehouse packs.

Prices, out-of-stock, and refresh

Same-day prices on each product page were observed 2026-11-01 for ZIP 90404 unless marked price pending (organic kiwi). Eight lines were out of stock when we checked but stay on the site for restocks (including organic ground beef, ground turkey, guacamole, bell peppers, fresh strawberries 2 lb, Di Bari pasta, SnakYard sweet potato sticks, and Bounty paper towels). Re-import after you edit the list: save a JSON scrape from the list page and run `node scripts/costco-main-list-import.mjs scrape.json` (writes `packages/hub/src/clusters/organics/costco-main-list.json`).

Download these lists

CSV files open in Excel or Google Sheets. Checklists are plain text you can print or keep on your phone while you shop Costco Same-Day. Each file includes item name, parsed pack size, Costco item number (when we have one), quantity 1 per line for a family of four at that cadence, category, and a link to our product page.

Build a saved list in Costco Same-Day

Costco Same-Day checkout is powered by Instacart. Menus and button labels change over time — use the steps below as a pattern, not a guarantee of exact wording.

  1. Sign in at sameday.costco.com with the Costco membership tied to your household. Confirm your delivery address and warehouse if prompted.
  2. Open one of the downloads above (or our category pages) and work through lines in the order you prefer — weekly produce first, then monthly stock-up, etc.
  3. For each line, search Same-Day by the product name from the file. If search is noisy, try the Costco item number from the CSV or checklist (numeric IDs from our import). Organic kiwi and other lines without a number must be searched by name only.
  4. Add the matching SKU to your cart at quantity 1 unless your household needs more of that pack size. Skip or substitute when an item is out of stock — our checklist notes lines that were unavailable when we last checked.
  5. After your cart looks right, look for Instacart's option to save the cart or order as a list(wording varies). Name it clearly — e.g. "Organic Main List — weekly" — so you can reorder later.
  6. On future trips, open your saved list or order history, load it into the cart, adjust quantities for what you actually need that week, then check out. Re-download from this page after we re-import the Main List so item numbers and out-of-stock notes stay current.
