It's already pretty easy to find and purchase products on Amazon, thanks to a wide array of apps and additional hardware like the Echo and grocery scanner. However, Dash buttons make things even simpler. Fix one to the fridge and every time you run out of your favourite home product, hit the button and it'll instantly re-order what you're after. In the US, the program is already two years old and spans over 250 different products, but in the UK, where the program isn't yet a year old, things are a little more sparse. That changes somewhat today with the addition of 20 new products that range from batteries and beer, to coffee and vitamins.
