You can not trust B&Q !!! They have on their website product (Anthracite Arnhem Paving Slabs) , which are available for home delivery within 7 days, so I went to the shop asked if they can make the order for me, because I want to be sure it will arrive in 7 days time, because I booked my builder already. They checked the product, and told me it will be available in 4 weeks time, because of supplier or whatever it was, so obviously 7 days delivery is a lying. Likely I didn't bought the slabs online, because it will be a big disaster for the builder. B&Q NOT RECOMMENDED !!!!!
