Constraints

Requires a Muse account; prepare the last 3 months of online grocery order history or photos of physical receipts. Constraints are "at most 2 stores" and "within a 20-minute drive." The author did not explain how order history is handed to Muse (upload/screenshot/linked account) or how Google Sheets authorization works.

What they did

The author sent Muse an instruction to find a cheaper grocery combination based on the last 3 months of purchase history, with two constraints: at most 2 stores and within a 20-minute drive. Muse read the online supermarket order history, organized regularly purchased staples and their cycles, compared prices for the same cart across nearby stores, and returned the optimal combination.

How it went

Author report: saved about ¥5,000 per shopping trip, roughly ¥90,000 annually. Muse also detailed the savings breakdown (e.g., half from switching drinks to a store-brand alternative), leaving the user to decide whether to adopt the changes. (author_report)

Worth knowing

The source does not specify how Muse accesses order history (API connection, file upload, or screenshot OCR); Google Sheets creation and authorization steps are not described; store price data sources are not explained. The quoted post from Gabe Hernandez is cited only as background, not as original material for this method.

Steps

  1. Prepare shopping history and set constraints

    Provide Muse with the last 3 months of grocery purchase records. If you use online supermarkets, share the order history directly; if you shop mostly offline, take photos of recent receipts and upload them. Also specify the two constraints: shop at no more than 2 stores, and keep them within a 20-minute drive.

  2. Let Muse organize staples and compare prices

    Muse reads the provided records, identifies regularly purchased staples and their purchase cycles (e.g., every 10 days, every 2 weeks). It then compares the total price of the same shopping cart across all stores in your specified range, and finds the cheapest store combination.

  3. Review Google Sheets results and confirm

    Muse summarizes the comparison results in Google Sheets with tables and charts. The author reports saving about ¥5,000 per shopping trip, roughly ¥90,000 per year. Muse also breaks down where the savings come from (e.g., half from switching drinks to a store-brand alternative), leaving the decision to you.
