I'd be more interested to know what your plans for a cage are for this snake, chain stores usually send people home with a fish tank, overhead heat lights, a useless half log hide and no thermostat, a bad overpriced setup all around that you will end up having to put a lot more money in to fix. I wouldn't buy from a chain store for the same reason I wouldn't buy from an expo, I like knowing the breeder and all info about the snake and don't want to risk illness or mites. There's no shortage of ball pythons around, you could find a normal for free to very cheap and there's many nice morphs that are inexpensive if you want to go that way. Just fully consider your options before buying, a snake is a pretty long commitment.
