Some people got caught up in the popularity of reptiles. I mean just check the evolution.
When the iguana became popular, everyone had to have one. Same thing with cornsnakes.
Now it's surinames and chondro pythons...
Some people will only look at it as the popularity of the moment and try to get a buck out of it.
I too love the cornsnakes I have and leopard geckos, they aren't worth much money wise, but damn they are so fun to keep.
I didn't start keeping reptiles for money, and I never will. I spend well over 300$ of food for my reptiles a month and the minute I will think they cost more than they give me, I will not keep them anymore.
