server must see the request and perhaps pick one of N responses.

I don't think I agree. I'm inclined to believe it must be part of
the key. There is nothing in current practice that I'm aware of 
which wouldn't allow GET of a URI to return a price list and POST 
of the same URI to confirm the order.
