Not sure if this is a local reduction, but they have plenty of these on the shelf and in their clearance basket. It's reduced to £39 in all stores (from the shelf label), but my local in Mill Hill East has it down to £25.99 with a special reduction sticker.
I picked up two a couple of weeks ago at £27 as they had them reduced to £33 and I had two "£6 off if you spend £30" vouchers, but this is even cheaper now. The extra bonus was that I had been sent an extra 10% off everything card to use as often as I like for this month, so in reality this got even cheaper!
Obviously it depends on taste as to whether you would like this whisky, but considering its normally £50 (currently £40 on amazon), this is a great Christmas present for friends, family or your doctor :-)
