Yeah you have to be careful with pet stores. The store I got my spider bp from sold her to me as a male and the sales person kept trying to tell me she was a woma ball python. Atleast I have a knowledge of what morphs look like, I just feel sorry for the people who don't and would just take his word on it. I'm lucky enough that I have a friend that can sex them for me because I'm still afraid to do that part so I know for sure that she is a girl and not a male.
I also have a greek tortoise that I got from a breeder that was well started and told me everything I need to know about proper care. However, I have went into the local petsmart and they have tortoises and they try to tell you that they are 2 month old captive bred babies (the last tortoise I saw in there was a red foot and it was atleast 8 inches) and that they only eat these colored pellets. I tell people to please do your research and try to get from a breeder if at all possible or a trusted store.
