I never had an issue with Amazon to return the product (even not damaged), especially if it was bought on Prime. I've return a couple of books with no particular faults, but not up to my standards of print quality. In your case, you have hard proof of bad print quality. I never experience Australian Amazon, but I've used US, UK, France, Germany and Japan with no issues. All of them had very flexible policy of product return, if it not up to par with your standards.
well, the problem was/is that I bought the book from Amazon US, and they shipped to my US address (I use Comgateway). This allows me to buy a bunch of stuff from US sellers and then have Comgateway consolidate the items into a singular box etc, thus saving shipping costs.
Amazon Australia wants nothing to do with it. Amazon US wanted me to ship it back to the US delivery address (Comgateway) and then they'd pay for the return shipping. Not really feasible for me, since the shipping costs from Australia to the US would be more than the price of the book...
So, I made it very clear that if Amazon US can't or won't help, I'll file a chargeback on my credit card. That got their attention and they ended up just giving me a refund for the entire purchase.
Of course, I'm not really happy, since I have a dud book, and now have to source a clean copy without print issues again. Amazon Australia has 1 left in stock according to their website, but I am wary of that, since Amazon's stock count is inaccurate at the best of times based on prior shopping experiences with them. And, high prices I might add. US price is USD $36 (around AUD $48). Amazon Australia wants AUD $60...shipping costs are higher too on the Australian site. Price gouging at its best.
Oh, and as expected, my 1 star Amazon review has not been approved by Amazon...funny that. Amazon is deliberately hiding 1/2 star critical reviews of many, many, many products, which I also suspect is in breach of US anti-trust laws. I have actually filed a formal complaint with the ACCC on this issue since I do not live within US jurisdiction. This is the 2nd 1 star review in the past 6 months (out of 2 reviews) that have been refused by Amazon.
I am most unhappy with Amazon - their service and customer service has taken a massive nose dive in the past 12 months and these days I typically try and buy elsewhere and avoid them. From now on, I'll be either getting most of my books from abe books or just simply EBay. Amazon is simply sub-standard now in my eyes. I guess Jeff [Bezos] must be desperate for more money...gotta fund the divorce somehow!
