Re: Every supermarket does it
The major supermarkets have expensive legal teams to ensure their "own brand" products (competing with major manufacturers' products) stay (just barely) on the right side of counterfeiting law. (Apart from the "bottom range" ones, that are designed to look like disaster relief handouts to persuade you to buy something nicer.)
And even if they are made for the supermarkets by a major manufacturer, you can bet your backside that they will change the recipe to make the supermarket's version "not quite as good" in order to protect their brand.
