I think it would be more appreciated if your prices were in bitcoins rather than dollars. After all, you are paying in bitcoins.
I think that in this precise moment, it's easier and safer to talk in dollars for this type of things, because of the changing price of the bitcoin. If it goes up or down you will get your U$D anyways.
That sounded all right until you got to, "you will get your U$D anyways." This is bitcointalk, not fiattalk.
EDIT: Not to sound rude. I am trying to say that most people in here are here for Bitcoin, not to get USD.
