From a conversation between Chris and me:
Chris: hmmm do you think that pricegroups belong logically under goods and services or under contacts? Or under their own top-level directory?
me: To me they belong to Marketing, or absent that, Pricing.
me: The fact that the price matrix isn't "visible" is weird to me.
Chris: yeah. visible as a menu item?
me: that and there's no overview of what's in a pricegroup.
