I'm looking for a price comparison script / solution.
I'm looking for something in PHP and MySql, but would accept Perl/CGI, Python and Ruby on Rails if necessary. I need something easily modifiable and translatable.
The script would accept .CVS, .XLS (maybe .XML) files containing items and prices from an admin panel.
A possible addon is a crawling tool that crawls the websites for new items/prices.
Need demo. No esthetic needed.
