If I could get one in the UK for nappies or wet wipes I'd buy in a heartbeat, the major factors for it working there would be that I have no choice as to whether I buy more, and it never being a good time to stop and order more the usual way.

If I'm fishing nappies out of the box and notice we're running low I'm almost certainly mid change, or preparing to go out, and I'll probably forget when do I get the chance.
