I have a berdie and he is 8 and should live about to 10 but some can live to 15 (mine was abused before i got him) they are about $50 as babies but you don't want to get one very young because when they are very young you cant hold them much or there skin will fall of is what i am hearing. http://cowgirl0216.hubpages.com/hub/All-About-Bearded-Dragons here is a site on it they get really big so please research them BEFORE you get one many people don't so their berdies will die. make sure that you get him/her from a good breeder look at reviews of the breeder and meet where they breed the animals DO NOT meet in a park or anything breeders who meet you places that are not your house may be hiding that they do not have good conditions for there berdies. Hope this helps! haha sorry it is soo long.
The average price for a Bearded Dragon goes between $50 and $100. The best location to buy them is from a highly regarded breeder, to be sure that it has been well bred and healthy, with a good size to sell. Their life cycle will largely depend on the care and upkeep.
