I am confused as to why billydan thinks the order was cancelled due to it being in Canada. The email does not say that, it simply says that the address you provided didn't meet their criteria. Maybe you had a PO box listed in your address. Maybe you used an abbreviation that made it look to them that you were in the territories. David never said, sorry dude we didn't think Canada was an approved country.
No PO box, no abbreviation. I used the exact same address for where my Nexus 4 was sent when I purchased it back in Nov.
As my address was clearly in Canada, and with them replying that my address (in Canada) was not approved, yes, this is them screwing up.....
