That guy who wanted each part practically AFA graded was clearly insane but what
about adding a few flags for sets whose value is considerably more than a few
parts.
I suggest
Box yes/no
Instructions yes/no
Complete yes/no
Or you could go as far as having mib and bnib as well. This would be great for
the wanted feature as we could tell demand for a set in a certain condition.
As price varies greatly between the different conditions and would differentiate
between a buyer who just wanted to build the set and someone who wants to keep
it pristine on a shelf.
