Quoted from T3quila:
I'm using now Pay Bill option from my Chase account - it sends a paper check on my behalf - I have PBR as a payee saved and I just have to change the memo with the current invoice number - works really well.
I'm doing the same. Steve turned me on to that a while back. The only check I was ever writing was to PBR. Since I went to Bill Pay, from my Chase account, I haven't written a physical check in more than a year. Saves a stamp too.
