Just something to think about, for a little bit more money you could pick up a more common morph(pastel is a good example) from a reputable breeder.
Either way I'd get a snake from somewhere other than petsmart. My one and only reptile I ever picked up from a big box store ended up being, and still is, a problem feeder.
A big plus for me purchasing from a breeder also is knowing that I'm supporting someone's hobby and passion, and supporting small business. On something that is likely to give 20+ years of enjoyment, what's another $20(heck what's another $100)?
