Whilst QAing bug 12310 I came accross the MungeMarcPrice routine inside C4::Biblio. This method does not appear to be called from anywhere in the current codebase and as such can likely be removed.
C4/Biblio.pm: MungeMarcPrice C4/Biblio.pm: $subfield_value = MungeMarcPrice( $subfield_value ); C4/Biblio.pm:=head2 MungeMarcPrice C4/Biblio.pm:sub MungeMarcPrice { t/db_dependent/MungeMarcPrice.t: MungeMarcPrice($price->{'string'}), t/db_dependent/MungeMarcPrice.t: MungeMarcPrice($price->{'string'}), It's used in sub GetMarcPrice. IIRC correctly, didn't follow the code trail, this is used trying to get a price from the MARC record when ordering from staged files.
