I wouldn't do that if I were you.

  1) read_shipping ref is in the Vend::Data package. :-)

  2) The assignment may or may not take effect, depending upon the
     module load order, assuming your module is read at all.

  3) Changing that ref would change the shipping routine for all of
     the Interchange sites on the server.  If you only have one site
     then its not a problem, of course.

  4) Yuck.
