I can't vouch for AWS, since I've never used it, but if the same principles carry across from their online store then one thing I've always found with Amazon is that they have the most amazing customer service.

I had an issue with a 9 month on SD card splitting, not expecting much I emailed them and they immediately sent out a replacement and told me to return the old one. I've had a couple of things go wrong with orders (sometimes just delayed in post) and they've always been very quick and helpful. Not all companies, online ot brick & mortar, understand this well enough.
