Our Wal-Mart carries aspen actually. It's about half the price as our local pet store. Hartz brand aspen, 1800 cu. inches (29.4 liters) compressed to 850 cu. inches (13.9 liters). It was I think about $3.49 compared to a similar bag at the pet store (different brand name) for $6.99. I'm still trying to find a local supplier though for even larger bags.
