Well I am still trying to use both in a site, but to be honest Interchange sucks... It hasn't got enough documentation, and customization is a big big problem. I managed to put links from php pages to interchange site by passing static item_id's. But I could not manage to get back. The problem is that Interchange is using CGI and PHP does not like that CGI.At the end I decided to rewrite whole shopping cart in PHP, and I am on it!
It is just fine if you learn programming interchange, and it will work for you, but I think it is not so much useful to know such unnecessary scripting language, especially if you need to spend days to understand manual.
Good luck if you insist on that. 🙂)
