Anyone who has been to an all time low concert...?

do they usually stay before or after the show to meet their fans? I'm going to one of their shows and there's a meet and greet the afternoon before the show but i'd have to buy an atl shirt or cd or something to get a wristband for the meet and greet but if I know that I'll get a chance to meet them at the show then I don't want to spend money for the meet and greet.
