Went to tractor supply today. For 9.89 I got a ~140 L of Aspen, 6.02 for 40lbs of Equine fresh and 3.49 for a 16 oz water bottle. Not too bad, just got all the mice in the tubs, we had quite a few preg females straight from the store, so I gave everyone a equine/aspen mix + a little aspen pile in one corner for a nest.
