I actually just had this conversation with my local reptile store owner..
Most breeders will sell their normals or possible hets to local stores for about $20-$35. Then the store needs to make a profit so they sell them for $50-$75.
It really isn't profitable to sell normals online due to shipping costs unless they are sold in bulk. This is babies though. Adult females are always worth more.
The problem with shows is that some people that are selling normals for $20 are selling imports. If you do not want an import or if you are not sure if it is eating and healthy, then it's best to buy from someone else.
