Editors get tons of stuff and tend to lose it all. Let your budget be your guide, but often sending an item without tracking can be money down the drain. Things do get lost, of course, and it can often take several days to find out if something was received or not and then correct it. Don't lose this valuable time. Send it right the first and only time. This also saves you from making time consuming follow up calls that only serve to distract both parties from the real story - your book - and toward your unfortunate shipping choice. It is worth the few dollars.
