Smells like a rat if you ask me.
If she was selling the pup in the UK, why couldnt I contact her from the UK? You CANNOT register a UK postcode on that site!!! I tried!!
Also, why did she put the amount on the add in £ pounds instead of dollars, as that is our currency!!
It also is VERY cheap, the cheapest I could find a yorkie for when I was looking was £200.
