The Sarah behind Supermarket Sarah started out creating shopping “walls” in her living room and moved upward and onward since then. Way, way upward. She now has a real bricks and mortar shop in Selfridges London, but she has far from neglected her online venue. The images below each represent one of Sarah’s walls, and her site is set up so that you can hover over any item for sale to get all the details and a price. How much fun is this? It’s online shopping in the most boutiquey sense possible!!!
