Intro to Marketing The discussion board this week focuses on channel intermediaries and their fundamental functions of transaction, logistics and facilitation. As we saw in the opening discussion in Chapter 12 (Managing Marketing Channels and Supply Chains) , Callaway uses Dick's Sporting Goods, Golf Galaxy and PGA Tour Superstores as channel intermediaries to serve a transactional function. For your initial post in the discussion board, please find an interesting example of a channel intermediary for a manufacturer and explain what fundamental function it serves and why it's important to both partners.
