I know rep is important, but I currently have none as a seller. I feel like I will be able to sell most of my first few clutches locally, but I don't want to wait a few years to prove my ph pied female since she will be ready to go next year (unless she goes on another 2.5 month hunger strike >_<).
I know genetic guarantees are pretty much worthless, but I will feel better sending them off with my snakes. I take pride in my collection and I have no problem giving a written guarantee of genetics.
