If there's a hard rule it should be: the more expensive item assumes the 
presence of the less expensive items.  Of course this will fail if two 
items have equal expense.  There is some leeway because we get to choose 
how to compare the expense of non-comparable items (like supermarkets 
and farmland).

Of course the system can fail if two items have equal expense.
