Thanks for that link, it helped me understand what AOPP is a little better.  What I don't understand is what it has to do with BitBox being a decent HW wallet or not.  Are they (or Shift Crypto) keeping records of who's purchased them or something?  Even if they are, that doesn't even sound like what the AOPP thing is all about.  I'm still a bit confused (but that's a normal state for me anyhow).
