You might have to phone your local ASDA's to check on their stock levels.
Aberdeen Dyce has this magnificent tipple at £30 a bottle.
It is listed as out of stock online but it's not the only malt whisky bargin they have.
Aberlour 10 year is 18 but with the voucher out of their " spend 40 get 40 in vouchers you get another 3 quid off.
Balvenie double wood £20 Balvenie signiture £23 ish

There are loads of others .... try their own brand Highland, Islay or Speyside; very nice !

What I'm trying to say is if you are a malt drinker take a trip to Asda ........

i find morrisons tend to have better offers on whisky, i missed out on one of the vouchers by 1 day though even though i had the booklet...so i'm a little bitter, some good deals if your store has them i havent personally seen their own brand ones instock in a long time.
