I buy most of my ball pythons from local breeders that I have a lot of respect for, and wouldn't dream of undercutting their prices. I'm a hobbyist breeder and have no desire for a profit, but keep and maintain a small collection, and wouldn't have a problem sitting on a snake until it sells at market price.

I personally also don't have a problem with people selling their snakes at below market prices... you made it, you can sell it for what you want. I likely wouldn't buy from you, and would be very cautious if I was buying a "cheap" snake from anyone, but you've got the right to sell at your own price.
