I think they sell all tickets! I went to buy my tickets at ticketmaster.com but another good website to order tickets is stubhub.com or something like that. If WWE RAW is coming to your city and you're sure of it go to a site that sells tickets.
I don't know what you mean by Pre-sale tickets but I'm talking to you about that you know when RAW is coming to your city. So once you figure out it is go to a site and buy the tickets.
If you aren't sure that the tickets you chose are good seats go to the site of where they will be hosting RAW - for example I wanted too see some good seats so I went to ticketmaster.com and found something that said something like section 118 or WHATEVER. ( I just made that up ) So then I saw that and went to AirCanadacenter.com because thats is the name of the my arena they were hosting RAW.
I went on SEAT FINDER (seat Finder is real) and then I typed in
Section 118
Row 7
( I just made that up but it might be real! )
So then it showed me where it was and lets say I didn't like it on the first try, which is true I think. So then i searched for other places until I found good seats. So I called the number you are supposed to call, pressed all the buttons I was supposed to that the auto machine on the phone told me too press them so I did.
Then after a month or weeks or sometihng the tickets came into my mailbox and on May I watched Live Raw that went on television and SNME ( Saturday Nights Main Events ) which wasn't live, it went on television in like August.
I enjoyed the show and if I didn't answer the question correctly sorry but anyway, I STILL DON'T KNOW WHAT YOU MEAN BY PRESALE TICKETS, I ONLY KNOW WHAT TICKETS! ARE
