Most companies that I know use "Postage" "Delivery" or "P&P" to mean the charge for postage & packaging etc... etc...
It is pretty clear to anyone who orders stuff domestically or overseas on a regular basis what a realistic & fair charge for this looks like.
Very occasionally extortionate "Handling" charges are slapped on top of this at point of delivery (in addition to any taxes charged). It amounts to a ransom on one's goods.
I think it is a rip off.
