Now I understand why some packages that I shipped to myself at my parent&#x27;s address didn&#x27;t get delivered and wound up at the post office pickup window - they don&#x27;t have a mailbox at the street address.<p>At least Amazon has been good about refunds and replacements when the delivery service has damaged goods - I&#x27;ve had books shipped in manilla envelopes with no wrapping left in a puddle under the eaves on rainy days, and electronics (also without protection) thrown in the snowbank.
