Your admission ticket to see a concert at Madison Square Garden could soon cost you an extra fee, even if you don't buy it from a scalper. New legislation is being proposed that would force venues to list all mandatory fees upfront in the ticket price, but the backlash from industry giants is threatening to actually raise base prices for fans. If this bill fails, your next trip to the World's Most Famous Arena might come with hidden surcharges that add 20% or more to your total at checkout.
