For me and 99% of people selling normal at shows or locally where most normal sell in general, why? Because, the chances of selling a $20 normal online with a $60 shipping fee is VERY slim, unless you find a buyer that has no clue on the market at all and is willing to pay $45 for a normal male and get it shipped. FYI you can get a pastel for $25/$50 a mojave, cinny, pin etc for $50/75
Normal are even sold as feeders that's how hard it is to move normal especially males. There is no demand hence the $10/$25 dollars price tag on an hatchling in the US and a $50 price tag for a proven female.
Knowing the market is kind of the things I have to do.
