I wonder how this would interact with various consumer laws. In Australia, for example, there are standards that prevent ticket sellers for events from being deceptive about fees - adding costs beyond a reasonable amount required to provide the service, etc. I'm not making any specific case, rather just feeling curious about how this impacts consumer rights and expectations. As a purchaser, I think it might be fair to know that $3 goes to apple when I buy a $10 cooking class using Facebook.
