Wal-Mart's UK Store Sparks Coupon Stampede

Savvy shoppers across Britain are anxious to see if their Asda grocery deliveries will arrive on Friday, after cashing in £50 ($80) vouchers accidentally issued by the supermarket. The Wal-Mart-owned chain launched a deal on Thursday which gave shoppers £50 off online grocery orders. Bargain hunters were quick to take advantage of the offer, adding £50 worth of goods to their basket, paying only for the delivery charge. News of the deal went viral on Twitter — with hashtags including #AsdaGate and #SupermarketSweep becoming popular — and Asda's website crashed as a result of the traffic.
