They can be purchased from both the Ticket Office and the Club Shop, and the draw will be made during the half time break in the game against Notts County this weekend.

You've only got until Saturday to buy your tickets, which are just £1 each, so don't miss out.
This year, there's a £250 cash prize, a trip to the training ground to watch the U's first team being put through their paces, Afternoon Tea, and a host of other prizes.
