How it works
We watch the shelf prices so you don't have to.
Costco doesn't publish warehouse prices online, and they change every week. We track them, do the math, and hand you the answer.
Track
Every Thursday we pull current shelf prices from three reference warehouses on the West Coast, Midwest and East Coast, and log every change.
Rank
Each item's label data meets its price. Protein per dollar, cost per serving and the week's price trend recalculate automatically.
Plan
A fresh 5-day meal plan is built from this week's best buys, with a grocery list that totals itself. Open it, shop, done.
What's inside
Six tabs. One spreadsheet. Updated weekly.
It's a Google Sheet you open on your phone in the aisle. Sort it, filter it, follow the plan.
150+ items across meat, seafood, dairy, frozen, pantry, powders and bars. Price, protein per serving, protein per dollar, cost per serving, trend.
Five days of breakfasts, lunches, dinners and snacks around 150 g of protein a day, built only from items in the Index.
Generated from the plan. Packs to buy, current price, trip total. Nothing to type.
Everything that moved this week, biggest drops first. The "buy it now" list.
New protein products spotted in the last 60 days, with a one-line verdict on whether they're worth it.
Every past week's plan and price snapshot, so you can see what a "sale" really is.
Why weekly matters
A "sale" is only a sale if you know last month's price.
Warehouse prices move constantly and the shelf tag never shows history. The sheet does. When something actually drops, you'll know the same day we do.

FAQ
Questions, answered.
Are these the prices at my Costco?
Probably close, but not exactly. We track three mainland reference warehouses (Los Angeles, Chicago, Atlanta) and show the median. Costco pricing varies by region, and Alaska, Hawaii and Puerto Rico run higher. Use the sheet to know what's a deal, then confirm at your shelf.
Is this a PDF or a real spreadsheet?
A real Google Sheet, view-only, that updates in place. You bookmark one link and it's always current. Sort by any column, filter by category, open it on your phone in the store.
How often is it updated?
Every Thursday: prices, trends, new products, and a new meal plan. Big price drops get added mid-week when we catch them.
Do I need a Costco membership?
Yes. The sheet tells you what to buy; Costco still needs you to be a member to buy it. We're not affiliated with Costco in any way.
Is this medical or nutrition advice?
No. It's price and label data, organized. Protein numbers come straight from product packaging. Talk to your own clinician about what's right for you.
Can I cancel?
Anytime, from your account page. You keep access through the end of the period you paid for.
