That is a correct price. Sometimes you can find someone to pay that for a normal...and yes, you see the adds for normals in the kingsnake classifieds for $40-50 dollars, but you keep seeing those same adds over and over because they don't sell. Eventually the person will give up and drop the price a lot, and finally the ad will disappear. Also, I don't sell to pet stores anymore, but I do know what they pay. Most pet stores in my area pay $10-15 for hatchlings 4-8 weeks old. They then resale the dragons for $35-40. You really can not even sell normal dragons over the internet unless you are selling a group of them, because no one will pay as much for shipping as they did for the lizard in the first place. They can just go to the pet store, and not worry about shipping.
Here are some ads from people that have given up their high prices, and just want out because they are going through 1000 crickets a day to feed them (in other words, it costs $50 a week to feed 20 6 week old dragons).
