Coupon code is IM1EFNSBL7, and should give you £50 off on your order. It came with an iBook/iPod promotion, but might be a general £50 off, I'm not sure. I'm going to go try it with an order for iWork ;-) Coupon expires last day of 2005.

(Update: Seems there's a minimum order amount for the coupon to work. I tried up to £100 and still no go, but if you're ordering a machine it'll probably work okay.)
