Constraints

Requires: supermarket app that emails digital receipts; email labels for filtering; shopping list service that Dot can sign into and edit; online weekly flyer accessible. Cost depends on Dot subscription plan.

What they did

The author fizzibitz uses a German supermarket app's electronic payment, receives digital receipts via email after each purchase, and labels those emails. The author then asked their Dot to download all receipts from 2026, extract the products, cross-reference them against the supermarket's online next-week flyer to find previously-purchased items on offer, sign into their shopping list service, add those items, and set the whole workflow to run every Sunday.

How it went

The author reports successfully configuring this automation (author_report). No specific data on first-run duration, error handling, or match accuracy was provided.

Worth knowing

The author did not provide verbatim prompts; the steps above are reconstructed from the tweet narrative. Email receipt formats, flyer website structures, and shopping list login methods vary by supermarket and region, so adjustments will likely be needed. Dot's capabilities for email access, web scraping, and login may change with product updates; supervised verification on the first run is recommended.

Steps

  1. Prepare email labels and shopping list account

    Create a dedicated label in your email client for supermarket receipt emails (e.g., 'supermarket-receipts'), and confirm your shopping list service is registered with login credentials accessible to Dot.

  2. Configure Dot to read historical receipts and extract products

    Have Dot access emails under that label, download all digital receipts from 2026 onward, parse each one, and store a list of product names you have purchased.

  3. Configure Dot to fetch the online flyer and match against purchase history

    Have Dot visit the supermarket website's next-week flyer page, extract all products on offer, cross-check against the historical purchase list from Step 2, and filter for items you have bought before and are now on sale.

  4. Configure Dot to sign into shopping list and add matched items

    Have Dot sign into your shopping list service using your credentials, and add each matched item from Step 3 to the list.

  5. Set to run automatically every Sunday

    Save the above workflow as a recurring task set to run automatically every Sunday.
