Screwfix is a great place to shop for everything you need be it trade or DIY. It is owned by the B&Q company although is actually cheaper than B&Q. Is in the style of an Argos, search through the catalogue, write down what items you want and take it to the till to pay. They always have a wide range of items in stock. Staff don’t seem overly helpful when it comes to taking your order but are pleasant enough. I would definitely always go here instead of the larger DIY stores as its cheaper and saves wandering round aisle after aisle trying to locate one item.
