I know this sounds evil, but for the moment, the best way to prevent screen scraping may be to use Flash. Flash now supports forms, submissions, authentication, yada yada yada.

This comment was not intended to address usability, nor the ability of non-Flash enabled browsers to purchase your product. But Flash is becoming pervasive, and is available on the platform that is most likely to be your customers browser of choice.

This will change, no doubt, as clients side Flash tools become as pervasive as various CPAN modules like LWP, etc. But for now, it seems to be the least likely method to address the issue you're concerned about.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
