A key concept in Drupal Commerce is the Product Display vs Product model used to separate physical products from their display on the website.
Depending on your point of view, this makes perfect sense or is a conceptual or practical nightmare. However you feel about it, understanding the reasoning behind the concept is essential when it comes to planning and implementing a Drupal Commerce project.
This session gives practical examples and demonstrations of setting up different types of products and product displays. You should leave this session with clarity about the architectural choices and with a set of stories for your clients ready for when you have to explain it to them!
