If you missed the AU's 100th year celebration, you still have a chance to receive a convention gift bag. Each bag contains AU yearbook, cap, cup, pens, paper pad, and commemorative coin. While supply lasts, the complete centennial set is available at $42 (includes US first class postage), a 20% savings when buying the complete set. Individual items sold separately as well. You can purchase just the 2010 Centennial Celebration Convention Bag for $6.00.
