NERD stands for New England Reptile Distributors...one of the (if not THE) biggest ball python morph breeders in the world. You should visit their site...it's really awesome.

Doyle...you'll get from them exactly what you order. If you order a baby, that's what you'll get. You'd usually be much better off ordering from ANY reputable breeder, rather than going through a petstore, which often has mites and unhealthy animals.

EDIT -- Also, you might check around for any reptile expo/shows in your area. Anything within a 2-3 hour drive would be well worth it. You get to enjoy the show, and then hand-pick the bp of your choice while talking with the breeder first-hand. (And at MUCH better prices than you'd ever find at a petstore, and without the shipping you'd pay to buy from the top breeders.)
