Paraphrasing from the recent "Supermarkets: The tricks of the trade"
episode of "Tonight":
A supermarket sells two kinds of wine, one for £ 3.79 (Brand A) and
another for £ 4.49 (Brand B), which differ only in quality. On
average, about two-thirds of customers buy Brand A and one-third buy
Brand B. Problem: Increase total turnover without cutting or raising
prices. Solution: Introduce a third and better kind of wine (Brand C)
selling at £ 9.99. It turns out that even though very few customers
will buy Brand C, about half of those who used to buy Brand A will
shift to Brand B, thereby increasing total turnover.
