Indeed, Work for the working man (If he wants good tickets to my show)

Also, if you don't mind gambling a little, you can always find tickets outside the venue on the day of the show offered by scalpers/regular folks looking to unload extra tix and usually at a loss as showtime draws near. With this being a stadium gig there will be lots of tickets to be had.
I hardly ever buy tickets to anything ahead of time anymore and always score good tickets at good prices outside the venue. You just need to show up a couple hours before showtime and see what they're offering.
