Tesco trailed in second with a basket that cost £1.12 more than Asda's. It was the only retailer to offer the Butchers Choice dogfood for under £2, however, and it also undercut its rivals on the Bulmers Cider at £1.24, fresh pasta sauce at £1 and new potatoes at £1.17/kg.
Sainsbury's Mr Muscle Bathroom Cleaner was down 46p thanks to a new promotion and it knocked 2p off Country Life. But at 65p its white rolls were the priciest.
Morrisons lagged behind in fourth, but still offered a basket for under £50. It made no hikes and its white rolls were at least 3p cheaper than its rivals'. It added 3p to the Green & Black's Organic Milk Chocolate and a penny to the soft scoop vanilla ice cream.
Waitrose's basket was over £15 more than Asda's. It offered the most expensive Bulmers Cider at £1.80 and pork chops at £5.98/kg.
