Or: you are a very famous American company, and you worry that you've tied up too much capital keeping inventory for retail stores at several supply depots in America.

This keeps me from panicking with last-minute worry that I've forgotten something, but it also helps me keep costs down because I have a sort of mini-inventory of travel stuff I need.

You also get newly manufactured product and dont have to worry about how long a part has been sitting in inventory or if it has been mishandled.
