While I totally agree with you, be very careful while doing this (especially buying tickets this way). There are a ton of scammers out there that will send you bogus venmo charges and take the tickets and run. Make sure they are a real person, who seems like they might like the band in real life.

There’s also an app called Cash or Trade that started in the jame band community. It’s a safe way to buy, sell, trade face value tickets. Not sure if there’s a ton of action on it for arcade fire, but it’s guaranteed safe.
