Exact same thing happened to me and my 2 mates- we got there about 11.35, joined the queue only to get totally shafted. HOWEVER persistence (or desperation) is the key- there were 6 reserved copies that weren't claimed. We got told that if no-one had come for them by 1am they were ours. 5 quid worth of sandwiches, cookies and fizzy pop and an hour of sitting around later we were smugly walking out with a copy each. I very much doubt it now, but there were 3 unclaimed copies that just went straight back into the warehouse, if anyone's still trying to source.
