I'm not so sure we should be having any costs at all if it's a quasi-constitutional right, as there are only a few of them. I think you shouldn't be asking for it. Government should be paying the freight. It does in any event, as five dollars does not cover the cost of a single request. In fact, it's probably creating five dollars' worth of costs to handle the cheque and process it.
