A week ago, I was told by the Ticket agent at the main Edmond's toll booths that when there is line up of cars waiting, to bypass the main booths, and proceed straight to the little toll booth at the beginning of the dock and purchase my ticket there before proceeding to the bike staging area at the front of lanes 1 & 2. If there is no line up of cars, that I could buy my ticket at the main booths, but that I would still need to stop at the dock booth and hand my ticket to that agent anyways. Long story short, at Edmonds, just go to the dock toll booth and pay there. Oh, and at the Mukilteo dock, ride down the "Local" lane all the way to the toll booths and then cut in to the left booth's line. there is a sign over that lane that says something like Recognized HOV.
