Waitrose offers a discount when buying multipack tins and tetrapack juices. For example, one tin of chopped tomatoes costs 45p, and a four pack costs £1.50, saving 30p.



However, the multipack tin comes wrapped in plastic, and buying four individual tins will cost more.



Waitrose should offer equivalent prices when buying the same multiple individual tins. This would help those who want to cut back on plastic use, or find the plastic to be extra work.

This should be a tiny change in pricing - something supermarkets deal with everyday. But to date, Waitrose has not taken on this suggestion
