Well, a better place would be
Reptile Depot or
ReptileKingdom.com: Reptiles, Amphibians, & More! ReptileDepot has amazing quality frogs and have a large number of dart frogs.
ReptileKingdom May not have dart frogs(not sure) but has the LARGEST selection of frogs iv ever seen, over 25 pages of them. Check Them both out before you buy from ATLfrog
