The reason I mentioned clearing is that the day that the bank sees the check is not the same as the day it is mailed, or the day that it is handled by the recipient. There are variables. If you are trying to achieve a decent financial status, you might want keep your cash in the savings account that earns better interest, instead of keeping excessive funds in the checking account. I'm engaging on this because I'd like to hear if there is some option besides having a benefactor provide me with a spare 'N' dollars to allow my checking account to have a buffer against the bank's unfriendly policies and the other random effects.
