I can tell you that most of those sites get paid for advertising on
the site and for referral business. On Amazon you can get people to
click through your personally identifiable link to the Amazon store
where you get paid a % of the profit that is made after a customer
makes a purchase.

Hope this helps somewhere to answering your question.

business model looks like this:

1) monthly fee for listing and/or
2) Pay-Per-Click (when you click on product to see more info on
buyer's site) and/or
3) small % fee for succesful redirection (ended with payment),

as for as technology:
1) you have to make XML file with description of all your products
(with prices). This file is uploaded automatycily once a day (more or
less). XML is some kind of standard, but in some situations there is
other synchronization method.
