I seriously doubt it.
Just because they say the handpick their stock from breeders doesn't mean everything they get from them is CB. Alot of the breeders in Fla deal with imports on a regular basis. Not to mention their prices aren't the best around.
Your best option is to go with a breeder and cut out the middle person. Depending on when your getting your Whites Tree Frog, keep an eye out here for me to place an ad to give away some CB froglets in the next month or so.
