I'll have to agree that the price thing is pretty tacky. And I do get asked all the time. Between good friends, ok. And on here, I get it, but complete strangers? I don't like to say, bc I got totally ripped off by a broker posing as a breeder.
I only think when talking about how much things costs, it's fine only if you think you got a great deal. Otherwise I think talking about price is tacky, esp if you are bragging about how much you spent.
