In short, their customer service.
Companies are bound to make mistakes. Orders will be misplaced, packages damaged during shipping, and products will malfunction or break. It’s how a company responds to those problems that makes them great, and I have consistently had a great experience with Amazon.
Most recently, I had an issue with a DVD I purchased. I had bought the I Love Lucy Complete Series (affiliate link) for my then fiance in October of 2010 (over a year ago). Well, since it’s 34 discs, we weren’t able to watch it all right away. In fact, we are just now getting close to finishing it. The second to last disc of the set gave us problems. It would not play properly, getting stuck in a loop on one of the production logos. We were unable to navigate to the menu or any other part of the disc. I checked the disc, and there were a couple scratches, which I know we didn’t cause because this was our first time handling it.
Since it was purchased over a year prior, I figured we were screwed, but I would try to contact the manufacturer. I checked the packaging, and found www.paramount.com/entertainment, so I try to bring up the page, but it doesn’t exist anymore. I can’t find any sort of useful link on the Paramount home page. I search for the CBS Home Entertainment website, which does have a contact page, but no contact form on it. They do have links to Twitter and Facebook, so I contact them through Twitter, and wait for a response.
In the mean time, I figure it won’t hurt to contact Amazon, since they are often very helpful, and maybe can at least get me in contact with the manufacturer. I explain the issue with the disc in an email, and ask if they are able to replace the single disc. I get an email within a couple hours letting me know that they cannot replace the single disc, but are willing to replace the entire set for me. They sent me a replacement, and are paying for the return shipping on the defective set. Their service is much more than I asked for, and certainly more than I expected, but why I continue to buy with confidence from Amazon.
