I ordered "Baby Bargains" from Amazon for my cousin when she was expecting. Unknown to me, she moved while the package was delivered. The tracking information indicated the book was delivered, but my cousin never received it and it was not forwarded. Amazon credited my purchase and express delivered a new book to the new address.
I was impressed. Even though I technically gave Amazon the wrong address when I purchased the book, customer service was very accomodating and took care of the problem.
