Words are inadequate

Note to self: shop at Costco. not Wal-Mart. [Too bad there's not a CostCo within three hours of here.]

So, everyone goes and shops and CostCo. Soon they end up being the biggest kid on the hill and demanding the lowest prices from their suppliers. What then, go back to shopping at Wal-Mart? If suppliers are willing to give in to demands such that it puts them out of business, that means another company with better business sense will take over in their place and not give in to the demands. That's how business work and it's been going on for as long as there have been businesses to compete with each other.
