It's the usual inflated price you'd find at a petstore. Even the top U.S. corn breeders (Kathy Love and Don Soderberg) only charge $25-35 for a baby snow. I paid $75 for a 2 year old adult - the older they are the more you pay.

If you really want it then I'd say go for it. They are beautiful snakes

Would this be your first snake (I don't see any listed in your signature)?
