Pushing all the right buttons
Not every Dash product can be reordered through an appliance. Some items - such as bar soap, condoms, tissues and razor blades - would still be tracked by the humans who use them. Thus, Amazon has steadily expanded its array of products that support the WiFi-enabled Dash button to order a predetermined amount of a home product with a single press. And its marketing is appropriately aggressive; Amazon refunds the full cost of the Dash button after its first use.
