I experienced an excellent example of good service recently.
I decided to invest in some software called ClickBank Download Manager. Basically, it has high levels of security in terms of preventing online products from being stolen. It uses very sophisticated ways of protecting your download links, and it works with PayPal. These are the two payment processors that I use.
So, I downloaded the software, and installed it on my web server. It's very easy to install. The only server-side requirement is that it must have PHP installed (most Unix servers do). And, despite it keeping a record of previous purchases, it doesn't use MySQL, which I found surprising.
However, when I started to investigate all its facilities, a few doubts came into my mind about how well it would meet my needs.
So I shot off a list of 10 questions to the owner of CB Download Manager, Sam Stephens, and I got a detailed reply back within the hour. And Sam is in Australia, where it must have been very late in the evening.
The result of this excellent service: win-win. Sam kept the sale, and I've got a superb download protection system which I now understand a lot better.
