SUPPLY and DEMAND
I have always found that when supplying to a market that it is best to ALWAYS supply what the market wants.
One trick is, if you cannot supply what the market want and have a good product nonetheless, then your timing has to be impeccable as to when you offer your product at your price, IF they are desperate.
Forget the discrimmination garbage, I work in the same area of supply, although obliquely, when hungry, they buy.
