There have been a few attempts in this space, but I would love Amazon to succeed here. I wonder if this is timed because of their purchase of Diaper.com/Soap.com. That business had a true understanding of how to sort and deliver merchandize. Seems like this would be a great way to leverage that knowledge combined with Amazon's inventory.
