"simply I know they tend to sell what I'm not interested in"
Hiding "tend to" seems inappropriate. Surely you don't mean it that way. There must be good reasons, not mere whim, to implement a suggestion like what you put forth.
PS - Unless you were trying to demonstrate hypocrisy, your smug arrogant nastiness is not appropriate. And we don't need a demo of hypocrisy, so either way, please clean up your own act.
