Just swung by the outlet mall in Gretna, that has a Nike Factory store.
Picked up a pair of black Pegasus 29+ Shield - they were priced up as ??43, which I was happy enough with. They went through at ??20-something, and then there was an additional 30% discount to come off because they were from the back wall.
If you fancy a punt, they had more 29s, also had lots of Pegasus 28, Pegasus 28 Trail, some Vomero 7, and various others. The guy at the counter said pretty much everything on the back wall was scanning at significantly lower than they were marked.
