What ticket route should I go. Please don't delete.

[trueceltic]

I am flying in from Seattle and get to Boston on Tuesday morning. I obviously can't get it mailed to me as I'm not staying in a hotel (flyback Wednesday morning after night out partying, hopefully). What is the safest route to go. I've seen other ticket agencies but not sure if those are legit. Any help would be greatly appreciated. I know I'm going to be paying through the roof for this but this scenario will likely never happen again with the Lakers and all
