I see it in a different way. $11 is a bargain to have support rep pick up the phone and bother to send you and individually prepared package. For phones that have been out of production for years.

Most companies don't bother keeping spare parts these days and if you, for some unknown reason, want to maintain your cheapish vintage cans, you should be AMAZED they still keep them in stock. Because they are definitely not making any money on it.
