Asda has launched a new service allowing customers to buy groceries online using their mobile phones. 

The new site also includes a mobile store locator, with maps and directions, as well as all of the features on the main grocery website. 

Kate Cuthbertson, Asda's head of mobile strategy said: "We know our customers want shopping convenience at their fingertips - so we've developed an easy-to-use grocery website, fully accessible from Smartphones, with the option to add or amend orders right up until the evening before delivery. 

"The mobile site was an international collaboration between Asda and the Walmart mobile team based in the US. We'll be constantly updating and improving the site over the next few months, with lots more interesting mobile developments to follow soon."
