B&Q have got a 15% off selected items weekend.
I have just gone through Quidco and they are offering 10% cashback after vat.
I have only seen this for the b&q spares before and not the actual b&q general site.
You would need to be a member or register. Obviously cashback is not guarenteed but if it tracks then every extra helps.
I hope I haven't posted this in the wrong place, I'm not sure if I'm allowed to post Quidco deals but thought people might want to know about this one.http://www.quidco.com/b-q/
