JLynn, I say this with kind intentions. Be cautious of sellers you don't know who tell you there's a lot of demand for their ducks. Work it the very same way you'd work buying a house. Have what you're willing to pay in mind, and don't let them think you're willing to exceed that because so many other people want their ducks. People will do this to increase the price, and there are a lot of sellers out there who do it, especially the smaller breeders. You want to be willing to walk away and tell her to call you if she changes her mind. I just don't want to see you be goaded into overpaying.
I say this as a seller. I do not do this to people. The price I set is the price of the duck/drake. I do not hold anything on a promise of someone coming over, and I do not bump the price up if someone else might want the bird. It is first-come, first-served, at the price I set. I sometimes negotiate down, but never up. If you get any feeling this breeder is doing that to you, walk away, please. I will send you some of mine at no cost to you other than shipping, which can be expensive on its own. I do not want to see you get messed over. I love BYC people and will do anything I can to help them. I'd rather see my Calls go to them and not make any money off them rather than see them go to a potentially bad home whose owner paid me for the birds.
