Build a household price comparison sheet

The job

Compare recurring household purchases using the actual unit price.

Before you start

Ask me for: A shopping list, preferred stores, pack sizes, and delivery postcode. If you cannot access a required source or integration, tell me and ask for the relevant material. Do not pretend to have checked it.

Instructions

1. Confirm the scope, inputs, and constraints with me before starting. Ask only for information needed for this task.
2. Normalize prices per kilogram, litre, or item. Include delivery and minimum basket rules, exclude unavailable products, and timestamp the checks. Provide a reusable comparison table without placing orders.
3. Separate confirmed information from assumptions. Include source links and dates for facts that may change.
4. Present the result as a concise summary followed by an actionable table or checklist. Include unresolved questions and suggested next steps.
5. Let me review the result. Ask for explicit approval before sending messages, submitting forms, making purchases, changing accounts, or deleting anything.

Done looks like

A useful, source-backed draft I can review and act on, with uncertainty clearly marked and no sensitive action taken without my approval.
