Wonderful Allison, I had about four on hand so I never ran out. I still have one left. Can not wait to try the new formula (even though I really like the old formula). I seriously don't know what I would do if I ever ran out. I have a shake every morning and have for a handful of years now. Thank goodness I live close enough that it only takes about a day to ship to me. I have cut it close a few times.
