All Orders to US Addresses Suspended Until Further Notice

Unfortunately for US Customers, and for my ability to earn a living, I cannot send orders to US addresses until the current situation changes:
* Most small business carriers have stopped selling shipping to the US.
* eBay has stopped selling Canada Post shipping, even though this is the only carrier that quotes on the postage most of the time.
* Entire trucks filled with parcels are being turned away.
* The carriers who will still try to deliver to the US are now requiring that the seller (me) pay all duties, fees, tariffs and taxes upfront BEFORE they are admitted to the US. The amounts are unknown, but can amount to more than the profit margin. An AI bot evaluates the commercial value of the goods in which 25% tariffs are due.

This is a completely impossible situation.

I cannot add the module to this website to block orders from US addresses, unfortunately, but I have disabled shipping options.

If a US customer orders and pays, I will hold the order as a credit to be fulfilled when the situation improves OR refund the amount paid minus the PayPal fees.
