Write a shopping list before you go

List what you need before you shop and stick to it.

Why it helps

A list cuts impulse buys and forgotten items, which means fewer extra trips and a lower bill.

How to do it

1. Check the fridge, freezer and cupboards.
2. Write what is missing, grouped by store section.
3. Keep the list on your phone or in your pocket.

Make it easier

Write only the five items you must not forget.

Make it harder

Add a spending limit for the trip.
