What they did

Do you know which store has your staples cheapest this week? This user keeps a Google Sheet of weekly staple foods. Twice a week, before shopping, their Grok Bot checks whether any high-protein items are on sale on Amazon, Trader Joe's fan sites and every grocery store within 5 miles. If something is cheaper on Amazon, it puts it in the cart and says so. It reminds them to photo the receipt, logs prices and quantities, warns when they're running low and sends the receipts to an expense bot.

How it went

A twice-weekly where-to-buy list, a pre-filled cart and a running pantry log.

Worth knowing

  • One Reddit comment, no savings figure. Store websites and apps sometimes block bots, and in-store prices can differ from online. Never let it check out without you.

Prompt

Cleaned version rewritten from the source — not a direct quote.

Here's my staples list: [Google Sheet]. Every [Tuesday and Friday], check prices for these items at [stores within X miles] and [online store]. Flag anything on sale, especially [high-protein items]. Tell me where to buy each one this week. If [online store] is cheaper, add it to my cart but don't check out. After I shop, read my receipt photo, log price and quantity, and warn me when I'm running low.
