Get a bottle of 4.01 and a 7.01 calibration solution.

I don't use a storage solution so can't really speak on that.

Get just 7.01 and use that for storage too. 2 point calibration only matters if you need accuracy to like .1 and we don't. If your pH is anywhere between 5.5 and 6.5 you should leave it alone.
