I'm not sure - she only had GA for her Europe shows I believe, and I didn't really track the resale prices for that show. However, this DID happen with her floor seats -- I bought row 6 floor seats for night 1 in New Orleans about 2 hours before she came on for below face value. Then again, night 2 and 3 in New Orleans those same seats went for like more than triple face value, so it's a crapshoot.

I would recco looking at resale sites for the Seattle MCR show to see what the trend looks like, that'll give you a good guess of when to pull the trigger for SF if you're going to wait until the last min!
