A new tie up between Sainsbury and Scottish Power could mark the start of the long awaited relaunch of the supermarket chain's loyalty card. Sainsbury is preparing to unveil a number of major initiatives that will reposition and reinvigorate its Reward scheme. And marketing director Sara Weller said: "The Scottish Power tie up is an early forerunner but the big news should break in the next week or two." Under the latest deal, Sainsbury cardholders who sign up to the Scottish Power gas or electricity offer, or who opt for Scottish Power gas, will receive 5,000 Reward points. {{NEWS }}
