i understand your questions, but am confused as to why you would ask some of them.

shopping at mac is like shopping at any store. you go in, see something you like, and try it/buy it. you can swatch it on your skin, or have an artist apply it on you, but a minimum purchase is required to have your makeup done. if you like it, buy it. if you don't, try a different color.

face charts are done after you get your makeup done. the artist makes them for you so that you can replicate the look at home. they don't charge you for them.

pro pans refills are $10.50. you can get them at freestanding stores, pro stores, and thru the #800. the regular mac chat wouldn't know the price since they don't sell them, so she wasn't dodging your questions at all.
