How many bottles do you have in all?
I have 250 in 30ml, 500 in 15ml, 200 in 6ml, and 100 in 3ml.
Most of them are empty, but since I mix my own, I buy the empty bottles in bulk. I'm actually running low on 30ml's right now as I started with 1000.
(I figured since most folks were answering with the number of bottles they had sitting around with juice in them I'd throw a curve ball into the mix.)
