for the RSG auctions, usually they send them via email attachment....unless the time is really close then they might fedex them ( in the beginning they used to fedex to us ).....the 15$ processing fee is essentially for them to provide an email with an attachment
we do not even think about that fee any more....we just know we start off at 210$ when we are bidding....
if you have won something other than an RCI gift exchange which most 7 day rentals are ......they might fedex them ( which then makes that 15$ fee more palpable )
