Sainsbury's ramps up price war

J Sainsbury has fired another shot in the supermarket discount war by matching Tesco with a buy one, get one free later offer. The offer, which has been welcomed by food waste campaigners, allows shoppers to pick up their free product when they want it via a voucher system. Sainsbury’s said its offer will also apply to bulky items like nappies. Customers will have a fortnight to redeem their free product.
