How long ago did you order your tix? They are typically mailed to you, but at only a week before the show, you may need to pick them up from "will call" at the venue (you'll need id and the credit card you purchased them with, usually).
My best advice is to send an email to the Ticket Team ( tickets@greatbigsea.com or help@greatbigsea.com) with your order confirmation number just to be sure.
Good luck, and have a great time at the show!
