Is getting a band membership worth it?

The band is A Day To Remember and i like them a lot! A membership is $20 and i would get stuff like drum sticks, a tshirt and a few other things. I would also be able to get pre sale tickets and be entered for a chance to meet them if i go see them (im seeing them in July) wat lind of other stuff would i have access to and is the whole thing even worth it?
