If you have products that cannot be combined in the cart (see
L<Interchange6::Cart::Product/combine> and 
L<Interchange6::Cart::Product/should_combine_by_sku>) then it is possible to
have multiple cart products with the same sku. In this case the arguments
to L</update> must be a list of hash references using either
L<Interchange6::Cart::Product/id> or C<index> where C<index> is
the zero-based index of the product within L</products>.
