Gotta Rant a Little

In one of the swaps I'm hosting, I get a pm from a possible swapper asking all sorts of questions which were (at least in my opinion) answered in the swap description.  But in trying to be a good hostess, I go ahead and answer them.  She shoots me another pm, with more questions.  Again, I answer them.  The third pm asked me how much something like this would cost to send (this being a smallish 'spa package').  I like to think that I am at least somewhat intelligent, but I cannot intelligently speak to how much something like that would cost to send.  I politely stated, that I was unsure as to how much it would cost because each were going to be different dependant on what was sent.
