this person on that website you gave is a broker not a breeder. A broker buys puppies wholesale (very cheap) from a breeder (puppy mill). The breeder (puppy mill) ships the puppies (many times in unhealthy conditions) to the broker who then turns around and sells you the puppy charging you way too much money for a puppy that will probably not be good quality (close to the breed standard). Unless you see the puppy's parents you won't know what your puppy will look like or how big he'll be despite what the broker tells you because the broker will tell you what you want to hear just to make a sale. Buyer beware!!!
Do some research on finding a good breeder then check out
www.ytca.org for breeder referrals in your area. That should be a good start.
I don't know how far you want to drive but there is a good breeder in PA that has beautiful yorkies and she's a member here. Check out her site:
www.sylvanyorkies.com.
Good Luck!
