Seems Autozone do accept International customers anyway! I got a form to fill out and email back to them, they would then contact me to verify the order.
Advance Auto Parts sucks though, been jumping through hoops today, called a relative in Cali to get their address, placed the order, and nope, doesn't accept non-US credit cards. Still, they reserved the money on my account! $261! Called them, and it was apparently just a verification withdrawal, no actual money would be withdrawn from my account.
