I looked at the lancasteryorkies web site. From what I can see, they do not breed the dogs. They are a referral service for over 70 breeds. They tell you they put you in touch with the breeders. If you are wanting to save money, paying a third party to direct you to a dog is not the way to do it. Lancasterpuppies can't do this for free, I am sure their fee for sending you to a breeder is built into the price of the puppy. It is heartbreaking to have a sick or dying puppy in your hands and have to frantically get help for it in order to save it's life. And the vet bills, well that is another story experienced by many on YT.
Please, listen to the information being given here and take heed. We don't charge for our services.
