Amazon Dash Button is a Wi-Fi connected device that reorders your favorite item with the press of a button. To use Dash Button, simply download the Amazon App from the Apple App Store or Google Play Store. Then, sign into your Amazon Prime account, connect Dash Button to Wi-Fi, and select the product you want to reorder. Once connected, a single press on Dash Button automatically places your order. Amazon will send an order confirmation to your phone, so it's easy to cancel if you change your mind. Also, the Dash Button Order Protection doesn't allow a new order to be placed until the prior order ships, unless you allow multiple orders.

The button is $4.99 but they are giving you $4.99 off your first order. See this link below.
