This is a fairly common occurrence in the real world, too. I knew a guy whose father worked for a company that manufactured windshield wiper fluid, which was packaged and branded in three varieties: budget, midline and premium. Identical product, three different price points, and all had good sales, because they were going after different market segments.
Not every sale is driven by "low price"-- in fact, in some segments, low price is a turn-off.
