I don't sell normal hatchlings to the public anymore. Since I don't do shows and people are not really willing to pay $55 to $75 in shipping for a $20/$30 animal I simply wholesale them locally for $10 a piece, this way I don't sit on them for months.
I will also offer free normal females with the purchase of any snake when available.
Now as when adult females are replaced by single, double and triple gene females, I usually let them go for $100/$150.
So here is how I price normal, in the end it really depends on the market around you, whether you do shows or sell online and whether or not you want to hold on normal and how long you are willing to hold on to them for.
