Well, if you are getting a job at a pet store... my first tad of advice... is wait and save your money, put some away towards a snake, and then you can get a really nice one from a good breeder.
then you also have a good deal of background on it, and you know it will eat good for you...
i just had to sell 3 of my snakes because i dont have the time for all of them... i like keeping mine handle able.. because i use them as a tool to help people get over their fear... so its a good idea to think about it for a while, and not rush into it.
