Amazon has launched its Prime Now one-hour delivery service in London, marking its first expansion outside of the US. The service, which first launched in New York late last year, promises one-hour delivery of “thousands” of items for a fee of £6.99 for Amazon Prime members in select areas of London. Two-hour delivery between 8 AM and midnight will be free. An Amazon Prime membership costs £79 per year in the UK, and the minimum order for either Prime Now delivery option is £20. Prime Now is currently limited to central areas of London, though the app notes that it will expand to different postal codes.
