In addition to the red flags KYS brought up, other red flags to me would be.....

No prices, and no quotes by email or phone message, voice only (No record of prices), and to try and make it look legit they say they cannot quote prices over the phone or email due to federal law (which law is that? I get quotes and prices through both mediums all the time)

No refund of deposits (we can sell the same dog to 10 people when the prospective owners get cold feet and STILL make a profit)

No show clause, which for people sellling theoretically purebred puppies seems beyond odd.

I wouldn't deal with these people for anything based on their business practices, never mind a puppy.
