The grocer will open a refillable section in a second store in Manchester city centre this month, which allows customers to replenish their own food containers from loose products including coffee, pasta and rice.

Top sellers included chocolate crunch cereal, whole porridge oats, basmati rice, milk chocolate raisins and Fiorelli pasta.
