Oh yes, I understood that. I still can't believe they're so rare that you can talk about the "most recent" one. And how would jimnotgym know? Most puzzling.

Note the phrase 'at our stores' in the preceding sentence. We don't know whether it's a couple of stores or a supermarket chain, but either way, it is likely that someone knows within any given enterprise.

Oh, I interpreted that as a patriotic way of saying "at British stores". Thanks for explaining!
