Many of us buy from Amazon on a regular basis. Amazon’s latest invention is designed to make it easier for customers to buy more things from it. The Dash Button has a reusable adhesive, allowing you to hang or stick it anywhere you need it. When you are running low on something, just press the button, and Amazon takes care of the rest.
Once you have gotten one of these buttons, use the Amazon app on your smartphone to connect to your home WiFi network and select the product you want to reorder. Amazon sends an order alert to your phone when you press the button. Best of all, these buttons are available for free to Prime members.[Source]
