The walls of Sydney's Town Hall Station are bedecked to resemble a Woolworths' supermarket shelf in Australia's first virtual supermarket, at Town Hall Station on February 19, 2012 in Sydney, Australia. The supermarket launched its virtual supermarket in Sydney's busy commuter hub to advertise the new Woolworths app, which will allow commuters to choose products, scan the product barcodes off the virtual supermarket wall, pay for their order and have the products delivered to their home or work.
