Feel free to link away but honestly the advice you will probably find here before even seeing the ad:
1. The housing they have it in is not entirely appropriate for the species
2. There may be feeding or health issues associated
3. For the price they usually ask on Craigslist you could pick up a very cool morph from a reputable breeder who will work with you, answer questions, and guarantee the health of the animal you buy. Where are you located? Is there a reptile expo coming to your area soon?
Good luck!
