I pay bills from my bank's website. It's just like sending a check, except you don't send a check. I have a list of the bills I usually pay (utilities, water, internet, blah blah) that I select from a drop down menu. If it's one of those regular things, all the address and account numbers and whatnot are stored and I only type in the amount and the pay-by date. I can also easily see when and how much I last paid last time.
I like being able to handle the bills as they come in without having the $ leave the account until it needs to.
It's super-easy. Also, if you give it a whirl and find you don't like it, you can totally go back to paper checks.
