Here is the flyer for the WSOPc stop in Florida at the Palm Beach Kennel Club next week.

Event #1 has three starting days and is predicted to draw as many as 3,000 entries with the $1mil gtd prizde pool. 3000 entries X $10 is an additional $30K unaccounted for Event #1 alone, which is not even the main event. You will clearly see no reference of any kind to the 'staff add-on' and no mention that you will not begin the event with the full WSOP starting stack. You get 9,000T for $555 and 12000T for $10 cash when you sit down in your seat.
They are using PokerTickets.com to give you the opportunity to pre-buy in for $555 online. The site that is pre-selling entries to the event makes ZERO mention of the staff appreciation add-on or the fact that $555 will not give you a full chip stack either.

The only place it is mentioned is on the structure sheet itself. Just a guess but I would figure that less than 5% of players would hunt down a structure sheet prior to the day of the event.
