“Thank you for doing this (suggesting a more affordable shipping option for a $4.95 accessory) –  The only reason I accepted is because it is small enough to fit in my mailbox.  Whenever it is too large I always use UPS or FedEx because I never have the time to go to the post office and I also have a concierge where I live that receives UPS and Fedex, but not post office mail.  This level of customer service is almost unheard of online and I appreciate it.  I will be certain to recommend your services to all my friends and their office managers as well.”
