This is just part of the reality of doing business today. I quote my standard rate for installation in these situations.

This ususally equates to a higher price than if they baught the system from me as a package. If they don't like it I tell them to call the internet catalog company who doesn't know a co from a PBX and say good luck.

You can thank your manufacturers for this.
They live under the delusion that if they have 20 dealers in a 50 mile radius instead of 5, they will make 4 times as much.

Allowing electric catalog companies who have ZERO knowledge of phone systems is just plain stupid IMHO.
