Amazon has launched a new ultra-fast way for shoppers to assemble and pay for their grocery orders, following the launch of AmazonFresh last month.

Amazon Dash enables shoppers to scan product barcodes directly from their fridges, or say the name of a product, before automatically adding it to their basket.

These items are then ready for purchase the next time they visit the website or mobile app.

Dash is available for AmazonFresh customers, initially at no additional charge, with their second AmazonFresh order.

“Whether a customer is reading a recipe or restocking their fridge, Dash allows them to build their shopping list without having to browse on a smartphone, tablet or computer,” Ajay Kavan, vice president of AmazonFresh said.

“We’re all used to trying to remember the contents of the fridge and kitchen cupboard and scribbling down reminders on pieces of paper.

“With Dash, at any given time, customers can keep track of products when they come to mind and scan to reorder groceries and household essentials as soon as they run out. At Amazon, we’re always looking to innovate based on feedback and Dash has been designed to continually learn as customers use it.”

AmazonFresh is now available for customers in 128 London postcodes. Amazon Prime members in eligible areas can order their full weekly grocery shop from a range of over 130,000 competitively priced products including big brands and offerings from local food producers.

One-hour delivery slots are available from 7am to 11pm, seven days a week, with same-day delivery available from 5pm for orders placed by 1pm.

The very first AmazonFresh order included Simply Chicken Skinless Breast Fillets, Growers Pride Mango, Farm Folk Thai Basil and Maynards Bassetts Wine Gums. It was ordered at 8.13am and delivered at 5.02pm to an address in EC1.

Best-selling products from AmazonFresh since launch include bananas, British Strawberries, beef mince, Morrisons ham, Morrisons British semi skimmed Milk and Pepsi Max (2L).
