Submit your store and organic finds

Our Costco Main List reflects same-day and warehouse pricing in a major California metro (ZIP 90404 as of 2026-11-01). Your club may stock different organic lines, or a local chain may beat Kirkland on unit price. We want those data points.

What to send

Store or chain name, city/state or ZIP, organic product names with pack sizes and prices you paid, and — if you can — how that compares to Costco in your area (missing SKUs, better deals, or a full basket that wins). Receipt photos help but are not required on the first message.

What we do with tips

We read every submission. We verify prices and primary sources before we add a store or product page. We do not accept payment for placement, affiliate deals, or paid referrals. Optional email is only for follow-up questions.
