Thanks so much for putting this together! I followed all of the steps and didn't seem to have any issues, however when I went to check a US Amazon short link (I live in Canada), it still took me to the US Amazon website. So I am assuming it is not working properly. Any thoughts as to why this might be? I don't have a VPN so I can't check if the other countries are working properly or not.
I'm assuming the actual link you're copy pasting for the product remains the same US link you get off your US amazon associates account, which is then linked to all the other countries. Let me know if that's wrong.
Thanks again for all of the help on this! It is so nice to have a workaround.
