Bread has been one of the fastest-climbing grocery items in recent years, which makes tracking promotions genuinely worthwhile. We follow loaves, rolls, wraps, pitta, bagels, crumpets, muffins and pastries at Tesco, Sainsbury's, ASDA, Aldi, Morrisons, Co-op, Waitrose, Iceland, B&M, Boots, Superdrug, Savers and Ocado (including M&S) every day. Hovis, Warburtons, Kingsmill and own-brand prices change often, so spot the cheaper week and stock the freezer with what's on offer.
