Many of the big breeders that you see in the classifieds and listed other places on the site do have normal cbb males and females for a reasonable price. Check out their web pages ask around - I just sold a pair of cbb males for $90 shipped. Buying from a breeder will also ensure that the snakes are established and clean and healthy - most breeders will also guarantee the health of the snake to some extent and provide you with any other help you need which is a lot more than you'll get from a pet store.
