Shipping doesn't always work
I replugged in the + 4 address again and then tried it without the +4 first address it worked without the +4 digits but the client wouldn't know this. I didn't try the Canada one but I am pretty sure since it is a non-standard US Zip that is what is causing it problems. Its possible the client didn't chose Canada.
The one from Canada seemed to be able to check-out without a telephone number which I couldn't replicate with all of the same information on her receipt. browngrotta.com
