LONDON: Amazon on March 4 launched its first “just walk out shopping” outlet outside the United States, as the online retail giant steps up its competition with traditional supermarkets and other retailers. Customers at Amazon Fresh in Ealing Broadway shopping centre in west London queued outside the black and green storefront under social distancing measures to be first to use the convenience store which has no checkouts. The outlet, according to Amazon, is the “first convenience grocery store to offer just walk out shopping in the UK” and its “first physical shop and grocery store outside of the US”. To use the new outlet, customers have to download an app and then scan a QR code before an electronic gate swings open and allows them to browse a range of Amazon-brand products.
