Coles or Woolies? Or both? Is it out of the realm of possibility ? Many products are currently stocked by multiple chains. Provided QBL can guarantee supply then I can't see this been a problem. Not sure what Waltana farming groups capacity is but wouldn't this be every QBL holders xmas's come at once. I'm still leaning towards a deal with Amazon based on previous hints in company announcements but then again I could be wrong. I still feel MCL has to demonstrate it's ability to harvest & package a quality product on a large scale before a major player extends a supply contract. Would be great to hear from anyone who knows how a coles or woolies picks suppliers, what sort of criteria they have to meet?
