Oh, by no means in my opinion did you overpay! It sounds like your breeder took very good care of her "family" which means better socialized, healthy puppies. At 8 weeks they are a little young to be leaving but with a lot of love and attention from you I'm sure that she is thriving. You can't put a price on love and don't even give it a second thought, your money will never be spent better!...
