Stay friendly, politee. The items you want to replace must be delivered within a 6 month range. Try to login to the persons email, using mail.email."net/com etc..] or by using http://www.dwmail.net/ Make a rule in the persons email to filter all Amazon emails, and be forwarded to the recycle bin. By doing this, the person will not be notified about the item you replaced, and therefore the changes of failure of shipping are much less.
