One Water in Africa

This is from the company that hired Brad Pitt for their marketing for this brand of water. I'd like to know what their markup is on the bottles and how much of that £1 goes toward 'administrative expenses'. My mum used to carry more than that inside a large clay pot, balancing it on her head whilst holding another one in her arms and walking three miles, half of which was up a very steep slope, so I am not impressed.
