Amazon is pushing a few different delivery services in the UK at the moment. Prime Now is a one-hour delivery service, spanning London, Leeds, Manchester, Liverpool and a bevy of smaller municipals. Amazon Fresh covers your everyday fridge requirements, including meat, seafood, fruit and veg, while Amazon Pantry is meant as a larder and cupboard-under-the-stairs filler. Together, these three represent a major assault on traditional supermarkets. You can't push a trolley around an Amazon store, but the company's argument is that you should never have to -- its delivery services are more than sufficient. (That's the argument, anyway.)
The Morrisons partnership is, in the short-term, beneficial to both parties. Amazon has an established, reliable supermarket partner, which can help to sell its vision of an online-only food delivery service. More Amazon Lockers will buoy the rest of its business, while minimising the costs that would be required with owning its own stores. For Morrisons, the deal is a chance to piggy-back on a highly aggressive, tech-savvy company. Amazon could one day threaten its own business, but for now it's a useful ally, one that could help driver customers away from its brick-and-mortar rivals.
