哪个卖used的傻逼，是他自己太傻逼呢，还是他觉得别人都是傻逼
有个商品，我实在不理解哪个used
Buy new: $729.99
14 new from $675.00
1 used from $750.00
有人能告诉我为什么吗？

1. some seller never check all the competitor's price.
2. some seller dropped price for new lately.
3. some seller sell new stuff but charge a huge shipping fee.
4. some seller just be there. after you click buy. they will not ship.
there are many reason used are more than new.

"beyond counting"
I sold new for 599. but people all want to buy the old version for 1000
dollar.
