I have seen many of these ads, and $ 300 always seems to be the magic asking price. They play on your heart strings with some story about living in areas that are not conducive for the puppy. This one says they are living in San Antonio. Does that mean there are no Yorkies there? I think not. Also, take a look at the wording. Appears to be someone who does not speak English very well. Most of the time, these ads are posted by someone in another country.
