Yes, that is exactly what we want to avoid.  Not only are the profiles
way more complex, they are in multiple pages in various combinations
depending on what is required.  Not only do we have to keep all the
instances of b in sync (easy) but all the instances of any combination 
with b (the hard part).  And its more like a..e unique "mini" profiles
in various combinations.  I bet it won't be too hard to stack and iterate
the profiles in Order::check_order.
