I save 39 cents in stamps x 10 bills every month because I pay all my bills via online banking.
OK, it's only $3.9 a month in savings, but I don't have to drive to the post office, buy stamps, and I never forget to drop the bills in the mail any more. And I save trees and free up time to do other stuff, like watch TV.
I use Citibank for my online banking, but almost every major bank has some sort of online banking available. Many of the payments are done electronically, so you can pay the day before a bill is due, in some cases. But check on that part.
