Frozen food is the quiet way to cut a grocery bill in half. Chips, pizza, veg, fish fingers and ready bakes keep for weeks and go on promotion constantly. We check frozen aisle prices at Tesco, Sainsbury's, ASDA, Aldi, Morrisons, Co-op, Waitrose, Iceland, B&M, Boots, Superdrug, Savers and Ocado (including M&S) every day so a family-size bag of chicken nuggets or a tub of ice cream never costs more than it should.
