Depending on whether you get from a breeder or not, HM and Deltas generally sell anywhere from $25-40 a fish here. A pair can set you back $50 - $100 if purchased from a LFS and slightly cheaper if purchased from a breeder.
A lot of LFS and pet stores don't sell all the tail types here. But a run-of-the-mill VT will set you back anywhere from $5-$10.
Females are in the same price range depending on tail type. However, usually all you'll find are chewed-up VTs.
Prices are generally fairly high as well for PKs, dragon scales, giants and dumbos as well.
