1. Unwanted gifts (seller found these people somehow)
2. Compulsive buyer emptying her closet of unused items, ok to lose a little, $200 over hefty retail price is nothing much
3. As mentioned before, a good quality fake. If you've been to South Korea, you'd know they make and sell counterfeits that look exactly like the original, down to the guarantee card and item serial numbers! Even the paperbags are exact replicas. These counterfeits are sold everywhere, even in shopping malls it has become difficult to ascertain authenticity even for the pros.
