I think people deserve to know every time I post a response to a thread that I am a dealer and not just threads where I make mention of a product that I carry. I could very well have a used piece of gear advertised here and then go on threads and in stealth mode to promote that piece. Not sure how many members may be doing just that.
So my advice would be for you to announce that you are a dealer every time you are on a thread. I am sure that would help your business.
