We've had this difficulty before, I believe. The clearance sale seems to include individual examples of items - either samples, used, or whathaveyou - that they're clearing out. Other places would have a bargain bin on the premises I imagine, but Rutlands doesn't have a physical presence for customers, so... The Mujingfang I saw stated it was used as a review plane by Andy King (for instance). i.e. One single plane. Maybe they should make it a bit clearer? Dunno. Anyway, that seems to be the situation. You snooze, you lose. :?
