I think the identification costs (and probably a few items) will LIKELY increase after we get off the island.
Since there are several good reasons why everything is so cheap on that island... SURE a Loremaster miiight charge standard fares to identify items...
But when everything is such garbage anyway and their fees would be more then most of the people on the island can afford... the price of a decent meal is a good starting point for what is less then an hours work.
