found it out
as for now only way to edit price range on derpi is to add an item in Item Sheet with intended price, thatprice said price will affect price range. As for me most expensive item is full-shade art, but it starting price is $50 with extras that can cost over $100 in total. Sooo... there's nothing i can do about it really except adding one extra item just to clarify highest price, which i won't do :D
