London 2012 Olympic Parking Permit Tickets Greenwich brough ?

I have four visitor permits for the London 2012 Games for parking in controlled parking zones within Greenwich. I have no use for these as I have my own resident permit. I have four of these to sell. It will allow you to park anywhere in the Brough of Greenwich during the games for as long as you want. These really are like god dust, you can not buy these permits! CASH only on collection from somewhere local to me - North Greenwich will do. thanks Price is negoatable and the highest price I am offered wins.
