www.stubhub.com I've use this service many times - and while you 'can' scalp - if you price right or take a little less then you paid - the sell through rate is excellent. I did this with my 2 extra GA's - sold them in less the 1 minute - printed the mailing label for Fed Ex (buyer pays) - and dropped them off. Time is running out to use this - as Fed Ex I think is the only option for using this.
You don't have to worry about meeting up with a buyer (wasting more time) and you don't have to worry about payment (nor does the buyer have to worry about delivery) as both sides of the transaction are guaranteed, if "the wrong thing is sent' buyer gets a refund, seller doesn't get paid. Only downside - processing payment takes a few days - although if paypal is used - seller I think get's paid faster.
I have nothing to do with any ticket broker/stubhub
