Any deals on Abbotsford Airshow tix?

Hi there,
I tried to do a search and couldn't find anything about this so I'm hoping I didn't miss another post about it.
Just wondering if anyone knows of any deals on the tickets for the Abbotsford Airshow this weekend. Adult tickets are $30 and children are $12 which makes for a fairly expensive day in a hurry. If you know of any deals, I'd very much appreicate hearing about them.
Just a heads up for anyone else planning on going, you can prepurchase tickets at SOF so you don't have to buy them at the gate, but the prices are the same.
