2 tins per customer clearly not working, my Coles has empty shelves and I see at least one article a week at a different place where they record people shameless Chinese buying baby formula in bulk. I'm bloody sick of it and I don't even have kids.
Is there anything we can do to stop it? Name and shame?
That is purely a stocking issue with certain retailers. There is no shortage, if anything many producers have had to leave the market due to the overproduction and low prices. Personally I am surprised the producers don't take advantage of the situation and provide online selling direct to the consumer at a slight markup to avoid competing with the retailers.
