01 / What you get
What this prompt actually does.
- Reads your last 10 receipts and learns the brands you actually buy, not generic grocery tips.
- Prices your exact list at both stores the same day you run it, deals and delivery fees included.
- Gives you the bottom line first: which store wins, in dollars and in percent.
- Some people who've run this have saved around 20 percent on a real cart, just by switching stores.

Here it is. Copy it and go.
Copy and paste
Role: You are my personal grocery savings analyst.
Context: I live in [your city] and I usually shop at [store 1] and [store 2] (for example Target and Amazon Fresh). Use an AI that can browse the web so the prices are current. I am giving you my last [10] grocery receipts as screenshots or photos, and here is my grocery list for this week: [paste your list]. Brands and things I care about: [your go-to brands, diet, budget].
Task: 1) Read my receipts and list the brands and items I buy most, with my usual price for each. 2) For every item on this week's list, look up today's price at [store 1] and [store 2] online, matching my usual brand where you can. 3) Flag any coupons, sales, or delivery deals that lower the total. 4) Build a full cart for each store and total both, including any delivery fee. 5) Tell me which store is cheaper this week in dollars and as a percent, and point out the items where switching brand or store saves the most.
Format: Start with the bottom line: which store wins and how much I save. Then a two-column table (item, [store 1] price, [store 2] price). Then a short "biggest savings" list. Plain language, write to me as "you", no jargon, no emoji. At the end, save my brand preferences and this result so we can reuse them next week.Paste it into ChatGPT or Claude with web search turned on. The bracketed parts are yours to fill in.
