I had removed it from this question: What is the procedure for adopting a purebred dog in the United States?, because it was more of a side-comment than a part of the actual question, but it made me think about whether it was something that could be asked separately or not.
It might be something that's included in "shopping questions", but it seems that because prices vary from area to area, and you even have the ability to bargain for a price most of the time, then questions like that would be off-topic for either being too-localised or too broad.
Are there any reasons why those types of questions would be on-topic?
