Paying at Canada Post loads your Bull account, you can then go online and buy BTC there.
All you need is a Bull account with an email and name, don't give phone number or address. - those fields are there for higher levels of verification but not needed for this under $1000.
The QR from your Bull account page is always the same, I made a paper copy and took that to Post Office for first try.
This is awesome for people in small communities and is cheaper than buying at non KYC ATMs!
