S-K Tickets

I ordered two tickets for the Sleater-Kinney show for tonight.

I bought the tickets through the 930club site and my total amount charged was $42.25.

(service charge of $9, 2 tickets for $39, and the shipping cost of $3.25)

However, at the top of the receipt, on the ride hand side, it says:

"Delivery (if applicable): Please pickup your tickets at the box office. If tickets are held at the box office, you will need to present a valid ID to pick up your tickets."

So, does that mean my tickets have been shipped to me because of the shipping fee (and if so, I havn't received them yet and the show is tonight..) or do I pick them up at the box office?

Thanks!
Just make sure you have your confirmation number and the box office folks will be able to tell you what is up.
