One thing I've tried to do is streamline the way I manage my money, and I accomplish that with technology; in addition to some great websites and services for managing money, I've tried to move all of my bill-paying online. If the place I need to pay has an online service to pay my bill, I use that, and if they don't, I simply set it up with my bank. In addition to being green, I have an electronic record of things I did pay or didn't.
Of course, I still have a bill I have to pay the old-fashioned way: my rent. Other than that, I have almost no use for my checkbook anymore.
What about you? Have you moved toward paying all your bills online?
