Your shopping cart was filled due to a mistake on the part of Harman's webmaster or whoever is in charge... is anyone in charge?
But seriously, even though those couple of line items were available, if you had phoned up a local dealer and asked him to order them, the response would have been, "We are no longer in the raw driver business, and no longer sell raw drivers other than a very limited number through JBL Pro."
I don't mean to belittle the real frustration you went through, but I'd say you were quite lucky to get any of the merchandise fulfilled. Every attempt I have made through "normal" channels has been declined.
