Your logic is sound, philipt631. But the reason that you know to load up on Pepsi's is that you first became aware of it via TV advertising, seeing it in a supermarket/convenient store fridge, it was first brought home by a family member, etc.
Since we likely do not have a large budget for big-time advertising, a rapidly expanding retail distribution is very important.
Unless, of course, they run some aerial banners at area L.A. beaches (and beyond) like the mocked up one I produced below...
