Here's the discount on the price point for my tickets - Dark Blue.
It notes on the seating chart they normally charge the same price for NCC & CONCACAF games at regular MLS match prices. For me that's $65/seat.
$141 for 3 games = $47/game. That's somewhere around a 28% discount. If I take into account the included taxes in the price it's close to $40/game/seat in my section.
That's about the max I would pay for these extra games in my section. Not sure I'm grabbing mine but I'm glad the TFC FO took time to think about how they would price these games.
