"Usually ships in 3-4 days" Does the phrase "usually ships" in these phrases not mean something? This is with reference to online orders I make at Amazon. When I get this info on a disk I plan to order, (24 hours, 3-4 days, etc), it can affect my decision as to what I order. I assume 24 hours means there is a nearby shelf with a deep stock of the disk, and 3-4 days probably means that it is in stock at a suppliers warehouse? But I often find that by the time the order has been placed, and I return to check status, the "usually ships" dates has been changed, ie from 24 hours to 3-4 days, or from 3-4 days to a much longer period. I would have thought the initial statement was based on links to a super-efficient inventory management system. But the frequency of changes suggests it is just a slippery phrase used to assuage casual customers. Am I right?
