I have seen Amber Marie and yes, she is asking higher than younger sp's. She is on Bby / Coq border near Loughheed Mall area. To me, she is worth the price. She has been reviewed a lot.
In New West, I saw a woman Carlita Jones near 6th and 6th. She is around her mid 40's a milf and fantastic down to earth kind of woman. I have not seen her ad in a while though.
