Heads up - B&Q at the North Farm estate are in the middle of a revamp (Toys R Us moving in, so the building's being remodelled to be 2 stores).
Last night there was a fairly large section of clearance stock going at half price or better - large piles of wall tiles and random garden things (slabs and the like). Sorry I can't give you an inventory - it is just random stuff. Odd tools too.
Cheers
Tim
