UK Grocery Price Drop Alerts (Apify + Gmail) with n8n

UK grocery price drop alerts—automatically emailed every morning (Apify + Gmail + n8n)

Monitor Tesco, Sainsbury’s, Asda, and Aldi product prices without manual checking. This n8n workflow uses the Apify UK Supermarket Price Scraper to detect UK grocery price drops and emails you a table of cheaper items—only when a price is lower than the previous run.

What this workflow does

• Runs daily at 7:00 using a Schedule Trigger.
• Loads your configured list of Tesco, Sainsbury’s, Asda, and Aldi product URLs (one per line) and the recipient email address.
• Calls the Apify UK Supermarket Price Scraper actor in product mode to fetch the latest price data for the listed items.
• Compares current vs last saved prices stored in workflow static data.
• Uses the effective price logic: loyalty price (e.g., Clubcard/Nectar when available) otherwise the shelf price.
• Generates an HTML and plain-text alert summarizing only products that are cheaper than the previous check.
• Sends the alert via Gmail only when at least one price drop is detected.

Use cases

• Get alerted when your favorite UK grocery items drop below yesterday’s price across multiple supermarkets.
• Track loyalty pricing changes (where applicable) and spot savings immediately.
• Build a simple “grocery deals” pipeline for SaaS operators or automation engineers who manage multiple subscriptions/monitors.
