Creating a 'Related Products' block with Views and Ubercart
A popular feature on e-commerce sites is the display of related products on the page when a user is viewing an item. This screencast shows how we create that feature with Drupal 6, Ubercart, Node Reference and Views modules.
There is the uc_upsell module http://drupal.org/project/uc_upsell which provides a similar feature.
This technique could be applied to any type of related content, we've just used related products as an example.
Please note: The sound level is quite low on this screencast, I'll hopefully sort that out on the next one!
