Free Online Checking Services

I have two separate personal savings account. One is for my retirement money and the other is my "payoll" money.  I use both of them online.  I check it time and again using my internet because it does not cost as compared to having to go to an atm where I will be charged for every inquiry that I do. So good thing there is Free Online Checking.  So I can compute time and again how much I spent for the day and how much money I have left.  Plus the fact that I also love to check it time and again since I am so proud of myself because I was able to save money considering the fact that I am a shopaholic.
