Sounds like a fairly average price iirc. As long as she's looking healthy and all. That would be my main concern. He may have paid that price to get them from a reputable breeder, but if not properly cared for then that can be more trouble than it's worth.

Garrick has a few somewhat similar snakes available for sale. From what I see, The super pastel super vanilla isn't quite as popular as a the vanilla cream or vanilla scream, but can be used to breed them or is a side product of attempting to breed them. The fire gene involved in the s/creams is a bit more sought after than the vanilla I think.

Most of it will boil down to being finding what you like. That's how I ended up with a killer queenbee when I was originally looking at a mystic potion. I saw her and couldn't pass her up.
