Thorburn understand the ingredients ,whether it be beer ingredients or plastic raw material or tin etc the real cost begins once you attempt to produce and package your product,otherwise the raw material component cost per product is relatively small,as proven over last 10 years from china very low eg.out door furniture etc I've been in manufacturing have you? Of course most understand a plastic product produced in australia may cost more than the raw material content in the same chinese product, but of course as i have posted before when china places their plastic s order it creates a global shortage for a month or two. So we need to rely on fresh produce etc.
