While this is not a sale post, I know people are buying Linkin Park presale codes at the Hollywood Bowl on 10/27. These are generic codes on ticketmaster.com. The Presale Code is LPOML
Hopefully this saves some people some money instead of buying a generic code from Ebay and Craigslist and allows people to buy their tickets early.
