I've seen pet stores sell a Normal for as much as $100 (actually $110 with tax). Here in Colorado at the shows they usually group them by sex and put them in multiples in show cases and sell them for $20 or $25, even more in other states. Wholesalers will give you $15 each and pay for the shipping but you have to have at least 10 of them. Using adult size normal females is a great way to expand your breeding operation at a low cost, they are cheap and if you spend more money on a good male they can be very productive. I actually have three Normal females and two normal het Caramel Albino breeders.
If you use a 'dull looking' five or six gene male you'll get a rainbow of different combos from those Normals. In fact I know that most big breeders tend to hang on to their Normal females, not only can you get some neat snakes from them you can also prove out unknown males. Even a large Normal male can sell for up to $100 and would make a fantastic pet. I have one Normal female that I think may be a brand new morph and I'm hoping to prove her out. If you have a keen eye you can pick up something brand new for next to nothing.
