this person is advertising selling English Bull dog puppies.  they want you to send 1/2 the money and they will fly the puppy to you and then you pay the other 1/2 when you receive the puppy.  I actually did not feel comfortable doing this so I offered to fly to BWI and pick up the puppy and pay in person.  this person agreed to meet me and never showed up at the airport and never returned my calls or text.

Because your seller wasn't even in North America. Did you know there are great pets down at your local shelter? You should check them out because you should NEVER buy a pet you cannot see or touch.

did you ever hear back from the person, or get your money back?

Sorry guess I didn't read that right.  You weren't out any money. But did you ever hear from them again?
