I feel that this represents a great strength and great weakness of the Amazon model. A huge network of independent sellers allows for an untouchable amount of variety and ultra fast movement in response to trends. This sort of grey market product sourcing model allows for value creation and low prices (these people are helping match excess goods with people who value them highly). But it would be impossible (with current methods) to control the sourcing provenance of these goods from such a vast network of suppliers at such low quantities. In some categories this can lead to the often discussed issues with counterfeits. Perhaps in the future a better method of the product authentication will allow the best of both worlds.
