Yeah, it's expensive.

No, I couldn't pass them up. Could be the last chance to see Postal Service (until the 30th anniversary tour).
Bush and Garbage I'd definitely see separate anyway. Some of the other bands are probably good live as well. So, $300 (with fees) for awesome seats for a whole day of awesome music, sounds very fair. (Just please don't charge us $10 for water and $30 for beer.)
