Why do people sell scripts?

[King]

Why would you say that the script isn't special? lol, look at both of them, and feel it if you've ever coded even a single page.

And the second answer of yours is worth a reply, that the coders would need more money to take their REAL projects to an end

A coder wouldn't be a coder then. They'd be an Internet marketer. I only looked at the first link, and the software involved was very simple. Many sites/services use a similar thing. For example, the Firefox search toolbar.
