Whenever you tap the Dash Button, various household items are automatically reordered through Amazon Prime and sent to your home.

So if you're out of say, diapers, you'd tap your Huggies Dash Button and expect a package to arrive within 48 hours.

Don't worry about button-happy babies ordering 112 units of paper towels. After the Dash Button is tapped the second time (or more) within a short period, you'll receive a smartphone notification and Amazon will require a confirmation to proceed.
