Why would you want to penalise buyers who had a misfortune of their items to go missing?  I buy many items on line and although the percentage that has gone missing is tiny, I have had several items not not arriving, or arriving via OSAKA, 8 weeks later !!!   In this moment I have 2 items seriously overdue.  As I am usually here when the postie arrives, I know there is no way they get taken out of my mailbox (big and locked anyway).  If these 2 items, from 2 different sellers, bought about week apart, do not arrive you would want to be able to block me?  ?:|
