Dash Buttons order single products with just one press
All customers need to do is press the button and the product will just pop through their letterbox within a few days.
The £4.99 devices connect to your wifi to make orders on Amazon.
Some of them are capable of ordering a variety of products from a brand, although customers need to go onto the Amazon website to choose which one the button will buy.
The most popular item among customers is toilet roll, with 300,000 rolls sold since June 2017.
