Amazon gave us a book's Pre-Publication price ($10.50) + shipping ($5.40).
A week later we sold our house and moved to a new address about 5.5 miles away.
I changed our shipping address before the Publication Date.
Along comes the Publication Date and Amazon ships... to our old address.
Pkg tracking shows carrier attempted delivery, but USPS already has our Mail-Forwarding Notice.
Pkg goes into Never-Never Land
We contact Amazon... who points finger at USPS
But Amazon ships another copy - overnight delivery - no charge.
Next day 1st book arrives after 10-day side-trip of PDX->Seattle-PDX, but now with $5.80 Postage Due.
Following day, the Postman delivers the 2nd copy, coming via Philadelphia, Sacramento, and PDX.
All this for a $10.50 book
I now have 2 copies to sell on eBay
... Buyer pays shipping - delivery not guaranteed !
