If anyone's looking for a presale code for the Guns N Roses show at NRG its: GNRHOU Use that in the "Promotions and Special Offers" tab when they ask you to enter your code. http://www.ticketmaster.com/guns-n-...artistid=735218&majorcatid=10001&minorcatid=1 It's limited to 8 tickets per Ticketmaster account. Presale started at 10am this morning and lasts until 10pm tonight. Still some pretty decent seats available last time I checked.
