My favorite example of this in Canada is a brand of butter that is shaped/looks exactly like a standard pound of butter when it sits on the shelf... but when you pick it up it's actually half a pound of butter... as it's only half as thick as you would expect it to be. It's usually priced higher than your average stick of butter as well. I picked one up once, laughed, and have actively avoided looking at that brand ever since. It's been on the shelf for years now though so they must be making good money?
