Why are red sided garters so expensive and hard to find?

I wasn't aware there was a difference between CA red sided garters and red sided garters (like I said I'm totally new to this). The reason I was so interested in those was for the bright red and turquoise coloring.

That answers the question as to which snake you were talking about.
Looks like Scott F. has a few for sale.
