Spotted these in Tesco this afternoon reduced from £10
It's a battery powered Black and Decker cordless screwdriver with 14 decent quality bits included , plus a set of 4AAs.
Being a quality branded tool powered by normal batteries it runs at 6v and it's got noticably more torque than a cheapo no-name 3.6v rechargeable one and you can just change the batteries when it goes flat. My experience of using rechargeable ones is that they always go flat half way through the job and are pretty useless , and if you want you can still use rechargeable AAs in this.
The only other place I could see selling them is Asda where they are £10 reduced from £15
