Is Amazon Dash Button an April Fool’s Prank?

Did you see Amazon’s latest release of their Dash buttons? You install these little physical devices around your household near consumable items. When you start running low on these items, push the matching Dash button and the item is magically added to an Amazon order for you to approve. 

Sounds like a nifty albeit prank of a product from Amazon. These buttons make sense for a certain audience, so I can’t tell if this is a legit product or something announced on the eve of April 1st. If you’re an Amazon Prime member, you can sign up for an invitation and see what happens.
