Saw this deal in HMV @ Silverburn, Glasgow yesterday. Trade in your copy of Fifa 10 on XBOX 360 or PS3 and buy the new Road to Fifa World Cup 2010 for £19.99.
It's the cheapest deal I've seen so far except for that dodgy looking Blockbuster 99p deal which I doubt will be honoured. I was hoping to buy it somewhere for 25 quid but this deal might be your best bet for now!
PS Instore Only.
