That would probably be better as:

sub getFiles {
    my @fileNames = ( 'manimp1.txt', 'manimp2.txt' );
    for my $file ( @fileNames ) {
        open my $FILE, '<', $file or die "Couldnt open file:  $file be
+cause: $!";
        while ( <$FILE> ) {
            chomp;
            my ( $key, @line_array ) = split /\t/;
            $newPrices{ $key } = \@line_array;
        }
        $count += $.;
        delete $newPrices{ 'Part Num.' };
    }
}
