+=item C<items>
+
+An array reference. For each line item this array contains a hash ref
+entry with additional values that have been calculated for that item
+but that aren't stored in the item object itself. These include
+C<linetotal>, C<linetotal_cost>, C<sellprice>, C<tax_amount> and
+C<taxkey_id>.
+
+The items are stored in the same order the items are stored in the
+object that L</calculate_prices_and_taxes> has been called on.
+
+For example:
+
+ my $invoice = SL::DB::Invoice->new(id => 12345)->load;
+ my %data = $invoice->calculate_prices_and_taxes;
+
+ print "line total of second item: " . $data{items}->[1]->{linetotal};
