Last year lasted into December but did sell out before the Dec 31 deadline. Buying tomorrow will most likely not be necessary, and since I'm going to be on a flight tomorrow at that time I sure hope it stays the same.
Last year I went to buy one on the last day of presales (31st) and it had sold out. I know I'd checked a few days earlier and they were still available then, so it definitely isn't necessary to get them as soon as they go on sale tomorrow but they might sell out before the presale ends again. I don't wanna miss out on saving 25 bucks this year so I'm buying mine tomorrow morning.
Even 2011 (Foo Dr. Garbanzohters year) presale was available for months and after the lineup came out it still took around a week to sell out, so unless things change drastically you won't have a problem getting a ticket if you are moderatly paying attention.
....and I call to ensure my address is correct because I made a typo, and now they're telling me that they have to refund my $10 I paid for UPS because they can't send UPS to Canada, and my only option is willcall.
I really really really don't want to have to do will call.
