Prime Now Expands in London: Number of Postcodes Eligible for One-Hour Delivery Increases Five-Fold

One-hour delivery now available to customers in Merton, Wandsworth and Sutton

Two-hour delivery windows available in Kingston, Sunbury and Croydon

LONDON — 6th October 2015—Amazon today announced the rapid expansion of Prime Now delivery in London. Following the opening of a new Amazon delivery station in Wimbledon, the number of postcodes eligible for one-hour delivery has increased five-fold and the number of postcodes eligible for a two-hour delivery window has almost trebled since the first day of the service in June 2015.

One-hour delivery via Prime Now is now available for Prime customers in Merton, Wandsworth and Sutton in London. In addition, Amazon Prime customers in Kingston, Sunbury and Croydon can now benefit from Prime Now for the first time through its two-hour delivery windows. Prime Now is available from 8 am to midnight, seven days a week. Amazon will continue to expand Prime Now across further UK cities before the end of the year.

"Millions more Londoners can now enjoy ultra-fast delivery," said Christopher North, Managing Director of Amazon.co.uk. "The service is proving very popular in the capital and we've seen high demand on everything from essentials like bottled water, coffee and nappies to the latest must-have popular items like games consoles, toys and sports equipment – all of which are available for delivery in less than 60 minutes."

In August, one-hour delivery expanded into Birmingham, Amazon's second UK Prime Now city where customers now have access to more than 20,000 products including a new range of chilled and frozen items such as Chicago Town pizzas, Birds Eye fish fingers and Ben & Jerry's ice-cream.

Londoners can choose from thousands of everyday items such as toilet paper, batteries and toothpaste, to last minute party essentials such as beer, snacks and fizzy drinks as well as other popular items like games consoles, gadgets and gifts, delivered right to their door in an hour or less.

The fastest London Prime Now delivery to date was a NETGEAR Wi-Fi Range Extender which was ordered at 10:32am, shipped from Amazon's Bow delivery station and delivered at 10:44am to a postcode in Canary Wharf.

All Prime members can immediately download the Prime Now app, available on iOS and Android devices, to find eligible delivery postcodes and request notification when the service is available in their area. Customers can also visit www.amazon.co.uk/primenow to discover eligible delivery postcodes. Prime Now customers can choose delivery within one hour of ordering for £6.99, or free delivery within a choice of two-hour delivery slots between 8am and midnight, seven days a week.

Prime Now is made available through Amazon Logistics, Amazon's technology and logistics platform that empowers independent local, regional and national delivery companies across the UK to deliver Amazon parcels to customers seven days a week. London Prime Now deliveries are made from Amazon buildings in Bow, East London and Wimbledon in South-West London.
