~Sparky~,
My main electrical wholesaler actively sends me to others if they don't have the kit, they know I will go to them first, but if they don't have it and can't get it at a competitive price or when I need it they will tell me to try xyz as they normally have this on the shelf.
This does not make me go to xyz first the next time, in fact it makes me go BACK to my first choice wholesaler as they are the helpful ones!
