Just a quick update for UK patrons. After purchasing the set in-store from HMV, I rang the number listed upthread. I was instructed to return my discs in person next week, by which time replacement stock will allegedly be on the shelves.
Honestly, I am somewhat sceptical on the successful outcome of this action - from both an availability and/or resistant/unwilling employees standpoint. I was clearly told those on the shop floor have been fully briefed however. Hmm, we'll see...
