Advice on getting a Yorkshire terrier at reasonable price please?

We would really love to get a Yorkshire terrier (young or puppy) but cant really afford to pay out hundreds of pounds and also quite weary of buying online off breeders anyway. Does anyone know of anyone who has had puppies and looking to send them to a loving home. They do not need to be pedigree or KC registered as we are not looking for a breeding dog, just a family pet for loving. Many thanks.
