This is about the best deal i could find for the upcoming FIFA 08 on 360.
£39.99 at Game for pre order (delivery on day of release)
use quidco link (11% off final price)
use your points card for £2.00 worth of points
use promo code GETUPANDPLAY for £5.00 discount at checkout
quidco works out at around £3.50 + £2.00 + £5.00 = £10.50 discount roughly!
total price £29.50 give or take a few pence.
You can of course use this principal for any game over £30.00 just used this example as i wanted to get fifa for the best price.
