Went into the old Liverpool Zavvi store last night looking for Sarah Conner Chronicles on Blu Ray and found these.
In the Xbox section they had 12 month Xbox Live subscriptions for £29.99 with 20% off making them £23.99 (thats what was on the shelf at least). They also had a selection of 2100 Points cards marked up at £15.99 with £11.99 after discount. I got two of the points cards but didn't bother with the sub as I've just renewed.
Quite a few other good deals with 20% off all xbox accessories, can't recall the exact prices but they had lots of headsets and live cameras going fairly cheap.
