Sam’s Tips
Open your grocery store website first, sign in, and choose your store plus pickup or delivery before you paste the prompt. Inventory, prices and package sizes vary by location.
Start small. Try this with 5–10 items before handing it a giant weekly grocery list.
Be specific about quantities. Instead of “pumpkin,” use “2 cans, 15 oz each, pure pumpkin puree.”
Tell it what matters to you, like store brand, organic, specific brands, allergies or a budget.
Keep passwords and payment information out of the prompt, and always review your cart before you check out yourself.
Shop this grocery list for me using the grocery store website I currently have open and am signed into.
Use the store/location and pickup or delivery settings I already selected. Do not change my store, fulfillment method, account settings, or checkout preferences.
For each item:
• Choose an in-stock option
• Choose the smallest practical package that meets or exceeds the amount I need
• Prefer the store brand or better-value option when the quality is comparable
• Avoid unnecessary multipacks or oversized quantities
• Add the correct quantity to my cart
• If the exact item is unavailable, choose the closest reasonable substitute
• If there is not a reasonable substitute or you are genuinely unsure what I mean, skip that item and flag it for me instead of guessing
My grocery list:
[PASTE YOUR GROCERY LIST HERE]
Work through the list autonomously and add the items to my cart.
DO NOT place the order, submit payment, or complete checkout.
When you are finished, give me a quick summary showing:
• Items added
• Quantities
• Any substitutions you made
• Anything you could not find
• Anything you were unsure about
• Estimated cart total
Then stop so I can review the cart and complete checkout myself.
