A price book tracks unit prices for your staples across stores so you can spot real deals and avoid decoys.
Why unit price wins
- Package sizes change; unit price tells the truth
- Track a dozen staples to start (rice, pasta, tinned tomatoes, oats, milk)
Setup (5 minutes)
- Create a sheet with columns: Store, Product, Brand, Size, Unit Price, Date.
- Log the prices for your top 10–15 staples at Aldi/Lidl/Asda/Tesco.
- Mark the cheapest store per item with a highlight.
Routine
- Record 5 items each shop; update monthly
- Use the Meal Planner to build around the cheapest staples
Tips
- Compare Aldi/Lidl vs Asda/Tesco own brands
- Watch seasonal shifts (butter, eggs, flour)
