I think there's a natural tension between departments that may have been in charge of their own purchasing before. You can imagine a natural response when the rules change and they say, “No, we're going to be doing it for you on these commodities.” It's a human response, so some departments have reacted that way--not all, by any means. Some are quite happy to work with us to analyze their purchases and take advantage of the volume buys we get.
So the experience is mixed. We've had some great success in some areas and a greater challenge in others.
