Now wait a minute here.
When writing up, placing an ad, who in the world is going to write a dictionary what the money is going to be used on.
There's no reason to do that.
At times when i place an ad in the alphabet soup, web sites, or on ebay, i do state my shipping charge is with insurance fee, and signature delivery fee, on the package.
Doing that to let them know, why the shipping charge is the way it is.
