Write a shopping list and don't shop when you're hungry!

Thinking ahead before heading for the shops is one of the best ways to reduce waste.

Start by writing a shopping list – and stick to it when you walk round the aisles. Ask yourself as you consider whether you are going to purchase a product “Do I really need this?” – and if you don’t, don’t buy it. And make sure you check the sell-by dates.

Try not to head for the shops when you’re hungry. It’s a well known fact that you will pile more things into the trolley in anticipation of eating them.
