I'm using the default catalyst controllers created with the Handel 
helper.  When viewing the cart I click checkout which posts to 
/check/billing

Ahh ok.   I've just done

                my $order_total = 0;
                for my $item ($order->items) {
                    $order_total += $item->total;
                }
                $order->total($order_total);

after  CHECKOUT_PHASE_VALIDATE, which works, although not very slick.   
It would be good to see a full blown Handel app to see some examples 
that "do the right thing", or better utilize the framework Chris has 
engineered.   There are a lot of building blocks available in Handel and 
I know I'm only using a fraction of them.  Actually, Mango might be the 
answer to that, eh?

Thanks again Chris.
