Didn't buy anything today. However, I got a flat on my bike so sooner or later I'll need another tube. Luckily it was the 26" and not the 29" that I was riding.
In other news, I was super productive on my dissertation today! Also, I was making PB @ Bread & Roses when the bicycle grinder broke so we had to grind about 9 pounds of peanuts by hand. Luckily I had some help. Good upper body workout.
