I can get then around 15 american but that is only becuase i am close with the LFS owner. he only orders them when i ask him too. because they are a special order he gives me an awsome deal.
The usuall price for a discus around shere i am is from 35 to 50 dollars american and that is for fifty cent piece size. Adults your looking about 55 to 80 dollars if not more a piece.
