Just went into my local Tesco (Hatfield) and they have their own brand tools reduced. Shelf edge labels with them so don't know if national or not. Still full price online. They also had:
Value drill for £4.99
Value Sander for £5.99
Power Force 4.8V Cordless Screw Driver SD48ZG £5.97
I know there not the best tools in the world but 1 year warranty if they break take them back.
No I don't have a reicept or a picture to back it up but would I really waste my time putting on here otherwise :)
