Sainsbury has been sending out coupons to Reward cardholders around the country in a bid to encourage them into Sainsbury stores. The scheme operates over three weeks, and offers customers four vouchers per week. These range from £1 to £2 off, when customers spend either £20 or £40. In an accompanying letter, Sainsbury claims customers can save up to £20, and encourages them to return to its stores. A Sainsbury spokeswoman said they did not want to give out any details but added it was something it had trialled last November. She said: "It's the first time we've done it on this scale and we'll be evaluating how it goes." {{NEWS }}
