I couldn't find information on exactly what the control solution was or what it did, so I figured I'd best get it. It turns out you only use a few drops of the control solution when you open a new container of test strips. If you order the AlphaTRAK 2 test kit, it comes with one bottle. You can hold off on extra bottles until the first is close to expiration!
