This is always a tricky management decision.
Although not managing any more, when I did through good and bad times I always resolutely stuck to my prices NEVER offering the individual customer prices which would undercut the brokers. The same gross price to all. Individual customers come and go but brokers are there for the long term if you build your brand.
It is such a basic principle of business that you need to establish your brand value with your long term customers, in this case the brokers. You will learn the hard way that in this business if you look after your brokers you will achieve longevity, if you discount to passing individuals you will pass with them.
A fool and his bags are easilly separated, never move home for a private owner etc etc.....
Best wishes to all ye brokers. I am not one but have been kept afloat by them when individual customers deserted with their sinking business.
