Well done Aidan,
I would have said the Glenlivet series too.
I recently acquired 5 of the series of 6 courses for my own personal collection.
The one which I do not have is Carnougie.
I managed to acquire these at prices of around €45 per bottle and four of the series have also recently been sold on Ebay.de for similar prices.
In this case, WhiskyAuction was just too expensive.
