When I got up this morning I had one sitting there, and then another one came through like 3 hours later! I think it does it in alphabetical order, so the lower down on the list you are, the longer it takes to get to you (it can only send out so many per hour or something).
ETA: The first one came through at 1:45 am to an email address that started with a B...the second one came through at 11:51 am to an email address that started with a D.
