How do I get tickets to next year's San Diego Comic Con?

-I tried a year ago to purchase tickets for this year's comic con, but the website was so slow, probably because everyone is on it. Is there another way to buy tickets?you wait like all of us who did not get to go this year hope and pray that they fix their website and tickets selling issues then you need to get very very very very very lucky lol. wish there was someother trick to it but thats it.
