HI, I have supported Pura milk in particular lightstart for as long as it has been on the market, over the past six months purchasing milk from Lenah Valley Caltex and Newsagency I have continously received milk that tastes half off. This taste evident even when first opened fresh and for over $4;00 carton I think is unacceptable. I therefore have started purchasing Betta milk and dont seem to have the problem, I would like to continue supporting national foods but not when this is occurring. jasonvinen @ bigpond.com.au
