Ticketmaster fees

Just bought some tickets on Ticketmaster and couldn't believe all the little fees that they add on. Why can't they just bundle these charges in to the ticket price? The "order processing fee", although it is added on to the "order" not the ticket, could also be bundled in to their overall costs. Make it a fixed cost per ticket rather than a cost per order. The "order processing fee" was especially annoying because when I was asked to select how I wanted my tickets (standard mail, express mail, pick-up, etc...) I chose standard mail because it said "Free." What is the "convenience charge" anyways? Just put everything together in to one fee and tell what it is up front. Break-it down later if you want.
