These newer ecommerce packages are getting way too big and complex. I want something I can understand , when I look thru the scripts. Have you looked at Perlshop? http://www.perlshop.org It's all perl, simple to understand and modify. It still uses a cgi-lib sub for getting params, but it can easily be converted to using CGI.pm. Perlshop supports a wide variety of cc cards, and you can easily make a custom cc verification sub for your special cases. It can be integrated with a database. It's free, you are free to modify it, it works, it's all perl, and it's still simple enough to understand. The guy who took over the sourcecode at waveridersystems, has an inexpensive addon called Office, which allows you to view order histories and print out shipping labels. Enough sites have been using it, without problems, that it appears to be pretty solid.
