I managed to get a couple tickets on Stubhub.
For anyone else out there looking for (almost) reasonably priced tickets, CAMP on stubhub*, refreshing every hour or so (phone app works great), I've been doing the same for the last couple weeks. Now and then some great deals pop up lower than all the other tickets for sale. Today I managed to actually buy one of those deals quick enough. It doesn't sound amazing, but I managed to get two upper sideline ticket aisle seats for $175 a piece.
Note for anyone who might be interested: In my obsession to get tickets to this game since single tickets went on sale, I was not only camping Stubhub (and a couple other sites), but I was graphing the total number of tickets available and average low-end prices. Tickets are not selling very fast. Stubhub had about 3600 available a week ago, and it only dropped by about 200 since then (it's actually been going up and down a bit). Furthermore, I've seen a lot more "quality seats" showing up in the $300-400 range. Knowing this, I probably could have waited another week for an even better deal... But, at least now the obsession is over.
*Stubhub has an alert option on the phone app, but there aren't many options. So, you'll end up getting handicap-only and standing room tickets as alerts. Plus, I don't think the alerts actually work that well. The tickets I got today were in my threshold, but I never got the alert email.
