House boards are not the best place for some of this info you can look at this other forum

but remember some people seem to have agendas of “keeping prices affordable” so take some of the info with a grain of salt. Flint is right to say have a preset amount and stick to it and don’t be afraid to try other ladies if the price isn’t right. Maybe you open with your price and let the lady tell you what she will offer for that amount.
