Woolworths and Coles have taken the Tesco model from Europe, oops UK, and used it to smash farmers. Our food is too cheap because the farmers are being screwed over. I support the farmer's options wherever possible. I make sure I read the labels and see what is being sold. The phrase to watch out for is 'imported ingredients'. That could mean everything from pig shit fed garlic from China through to mafia poisoned oil from Spain. It takes a bit of extra work, but at least you know you're doing the best possible for your digestion and well being.
