I went to the Stevenage store and managed to get dotmac for £15. They had a couple more of those left and 1 copy of iWork left for £15 as well. The only hardware they had was a Cinema Display but I didn't look at the price.
The person I spoke to at the collections desk said they have had people ringing up all the time asking what they had left and he told me they did have a MacBook but they needed to send it off first because keys were missing.
If you fancy picking up sme more dotmac boxes i'm sure I will be more than grateful.
