Asda glitch gives customers £50

Deal hunters have been cashing in on a glitch on the Asda website. Two different vouchers were released, one which offered £50 off any shop over £50, and one which offered £25 off any shop over £25. The news spread like wildfire, and hundreds put in a number of bulk orders of everything from alcohol to cat food.

So what happened, and can you take advantage?
