Also, if you buy the $400 GoPro Hero through amazon prime, and there's an issue with it, they will ship you a new one before you drop yours, for free return, into a UPS box.
Recently I ordered a light fixture with a glass shade and an Intel CPU at the same time. Apparently Amazon decided to package these two items together to ship them to me via Prime. After a few days I checked the tracking info and found that FedEx had returned the shipment as damaged before it even entered the state that I reside in. I decided to wait to see what Amazon was going to do next.
Five days after the "guaranteed" delivery date I received email from Amazon saying that "A shipment from your order (#xxxxxxxxxxxxxxxxxx) for the following item(s) has been returned as undeliverable ... If you haven't already requested a replacement order or received a replacement notification, you'll receive a refund notification soon, in which case you may return to our website and place a new order."
They then refunded the price of the CPU. I waited a few days more to see whether they were going to add on a refund for the fixture. No. So I emailed them to note that neither the fixture nor the CPU were delivered to me and that I'd appreciate a refund on the fixture also. They then promptly refunded that.
I was curious about the "extra month of Prime" that I had read about on other discussions so I waited some more, but no, no such offer was forthcoming. This time I didn't write to Amazon to ask.
I didn't reorder the fixture yet but I ordered the CPU for $20 less with free shipping from Fry's. And now it's backordered from there :-)
So what is my point? I digress.
