Just had a look for you and there are some pretty nice drops on offer in the supermarkets right now.
Old Pulteney 12 Yo £25 from Asda. There is no reason why everyone on here should go and buy a bottle of that at this price. Very good whisky and often found at this price
Strathisla 12 Yo £25 from Waitrose. Again absolute steel for the money, only you probably don't have a Waitrose on your door step.
Aberfeldy 12 Yo £28 from Tesco. Very decent. As with the three above all good introductions to single malts, nothing obnoxious about them.
Now for the devil in the pack, this is marmite of malt you'll either love it or truly detest it. Smoke and iodine spring to mind but at £26.50 a bottle of Laphroaig 10 yo going at Asda is a good deal, be careful not to get the bottles mixed up and leave with the Select which goes for £25.
All of those bottles are usually £35 + bottles of scotch
