Selfridges has announced the opening of its Christmas shop, available in London and online at Selfridges.com, with a selection in Manchester and Birmingham. Selfridges Once Upon A Christmas will build on the retailer's on-going commitment to change the way we shop with half of all products, including decorations, crackers, cards and wrapping paper having one or more sustainable attributes. The new sustainable collection features dozens of brands including many artisan and small enterprises, often UK and will be the largest sustainable collection Selfridges has ever sold from its Christmas shop.
