I am a shop that has a account on file with a BMW dealership in delaware. I could not uses my information that is on file with a dealership that told me they had a part I needed for a customer. So I drive there and they wanted me to fill out a complete form again just to use my discount with them. I know for a fact they deliver parts to each other . Hell with the small guy.
