Are you guys buying BAC every month?

From reading, BAC has a shelf life of 28 days once opened. Opened. The smallest I'm finding is 10 mL of BAC, I only need about 1-2 mL of it per month.

I bought a 25 vial package of Hospira BAC water. I plan on using each vial for 60-90 day periods, then discarding them.
