The Unpurchased Gadget

You know this kind of object.
The one that promises to simplify your life, but quickly ends up forgotten at the bottom of a drawer, between an old HDMI cable and a suspicious battery.

The Unpurchased Gadget is the most practical version of this gadget: it doesn't exist.

No object will be sent. No user manual will be needed. No incompatible cable will be included. No after-sales service will be provided, because there's nothing that can break down.

You pay not to receive an object that you won't need to put away.

Content delivered: nothing.
Battery included: no, since there is no device.
Risk of ending up in a drawer: nil.
