I want to list products on amazon.com that will ship to Canada (I don't want to sell on amazon.ca)

1)For any seller who has done or is doing this, can you buy international shipping on amazon and is USPS an option?

2) Will this offer the same protections as when buying shipping on amazon for domestic orders? I am referring to customers claiming they did not get an order, and if the label is bought on amazon, they can file a claim and amazon refunds them, not me.

3) In my experience, it is common that shipping to Canada can have delays, sometimes taking up to a month. If the delay is longer than the expected delivery date, and the tracking shows it is on the way, and the label was bought on amazon, what does amazon do? I don't want to be in a situation where amazon refunds the customer and I am out of pocket for the order.

Thanks
