In the end though, I doubt costs will actually drop. TM/LN, and others, can display the full cost of a ticket up front, instead of hiding the fees until the end at checkout, and nothing will change. TM/LN has to make money for their services and sites, and it doesnt matter how those costs are displayed, they need to make that money.
TM claims their value is justified in their service, yet when Swift's tour a couple years ago went live, countless people who were supposed to have access to tickets were screwed because TM's website screwed up. Its the very opposite of what they claim.
