This reminds me of a story a teacher of mine told in a Advertising class, about a retailer that put pressure on a soda maker to lower prices, or they wouldn't give them share of shelf. Well the soda maker didn't agree, so they pulled the inventory out. Weeks later the retailer came back to invite them in at the same rates. Apparently the customers weren't happy that their favorite soda wasn't available, and made sure…
Both companiese "seem" to be doing fine AFAICT. Most people I've asked seem not to care. I'd love it if they did care since the store branded products are not as good IMO.
