If the item is not available it local store DO NOT BUY ONLINE.
Ordered external door online (was available for home delivery only in our postcode) 4 days ago as I was paying for delivery anyway ordered tin of paint and some screws. Paint and screws were delivered the door is not in stock (hopefully will be next Monday). Needed it for tomorrow. B&Q can not replace it, the oder have to be canceled. SOO I just have payed £10 for the delivery of 2,5 l paint and 2 packs of screws. Lessons are expensive...
