Most pet stores do not sell anything but normals that are either bought wholesale from large breeders or are imported. Also hets and poss hets normally come with paper work to back up there genes from breeders. Hets are only as good as the breeders they come from too. Hets for the most part do not show what genes they hold, and hets look like normals. Only way to see is to try and prove out the snake by breeding it and to be honest I think you got ripped from a pet store who was just looking to make a sale like most are. They will tell you anything to get you to buy something from them~just like a car sales man.
