Anonymous users cannot see listed Commerce products in a View with a relationship to product Commerce products when listed in a View with a relatioinship to Commerce Products cannot be seen by anonymous users. I am using the Views Reference module in the product display and the View is not showing up when logged out. I cannot seem to find any permissions relating to this setup.
By default commerce products do not give anonymous permissions to be viewable. This is the reason when a View contains Commerce product relationships it will show nothing when your logged out. You will have to give users the permission setting:

--- View any product of any type ---
