I've made a webpage for an event and on the ticket-selling platform they've also made a page. There's a lot of redundant information between the two. I'm finding it hard to decide if it's a good idea or not to deduplicate the information.

Personally, I would just have the information on the webpage and on the ticket-selling platform I would just sell tickets. The platform would have a link back to the webpage for people looking for more information.

It could be the opposite: the ticket platform could have all the info and just embed their iframe into a page on our website.

Anyway, the job is done for this time but I can't stop thinking about it :) Any thoughts?
