I live in Israel, I can send them a message for you. But my thinking is that if they only accept messages from those 4 countries, perhaps they might only wish to ship to those 4 countries? Send me a private message with their information and what you want me to ask them. I’ll also ask them if they ship to Canada.
If they won’t ship to Canada, then you’ll need to find someone in the countries that they ship to to accept the package and send it to you. I’ve done that before a few times when I was living in the US and only wanted to ship to the Continental US and the Buyer lived in Europe. I had them get me a US address to ship to and that person handled the shipping to Europe.
Because of our current situation here in Israel, I would not feel comfortable being the party to accept a package on your behalf and then ship to Canada. As we are in a war on 7 fronts by many of our neighbors, not everyone loves us, and I fear that when someone sees Israel as the destination address, they might accidentally on purpose mishandle the package. However, Cypress is very close to Israel, so the shipping to Israel wouldn’t be so bad except you have to add 17% VAT to the item cost + shipping.
