On the order form, they will list the shows for which they have tickets. Therefore, you will not write "Chicago" and hope that they give you a ticket to one of the Chicago shows. Rather, you will select the exact show (date and venue) you want to attend.
PLEASE NOTE: If it is not on the order form, then Propaganda does NOT have tickets for it. In other words, you will be UNABLE to write in "the second Chicago show" on the order form. If you do this, you will NOT get tickets. This is because Propaganda onlyl has tickets for the confirmed dates at the time they mail out the forms. If second, third or fourth shows are added, often Propaganda isn't even given tickets for those shows. In other words, what you see on the order form is what they have available.
My tips: Do NOT forget the self-stamped addressed envelope. DO have alternative dates/venues in mind (that is, if you cannot get tickets for the show you want, what is your second choice - and remember, you can ONLY choose from the dates listed on the form). Do NOT forget to send a money order for the EXACT amount. DO send the form back by the due date and then be patient. If you follow all the directions, you should get what you seek.
