They may not want to hear what we have to say when a problem arises. They showed that they don't care about us when they decided to sell directly to the public and when they offer a 30% discount on all of the the products at a time of year when we're busy anyway, add to our customer base with holiday sales and compete with other CI and retailers, we shouldn't be forced to compete with manufacturers, too. If time allows, I'll do jobs that are pure labor- I make money doing that but I won't make a habit of it unless I have some kind of medical episode that causes me to want to deal with different equipment on every job- we can't know the intricacies of every brand and model out there and nobody should try. Knowing the fine points of what we sell sets us apart from the big box stores and many other retailers and that allows us to do what's known as 'Custom'. They don't really cater to what we do- they want to push boxes and make setup easy, so we aren't needed by their customers.
