My rule is don't let the price make the decision. Go on the health and appearance. Make sure it has plump eye turrets, look at the floor of the cage for a dump and make sure it looks normal. Make sure that the lighting in the store is all correct ask them if they have been supplementing. Look for swollen joints or abrasions.. and last but not least just make sure it is the chameleon you want.. because if not you will probably be buying another in 2 months lol..
