The other day in our local SuperValue their 2 litre milk cost $3.39 and their 3 litre milk was $5.59. What's wrong with that? The larger 3 litre milk is actually 10% more expensive than the same brand 2 litre milk. I think this sucks (as my kids say!) as most people expect the larger size to be better value and not everyone can work out on the spot that they are being ripped off by buying the larger size.
Is that just tough luck on them?
