I list on eBay.com (both auctions & store) and I do the same as whoscloset.
I specify in the shipping to USA customers: Standard Delivery, Expedited Delivery
I specify to Canada: (International delivery): Expedited Int'l Delivery, because we don't have cheap shipping in Canada as you all know.
I specify to Worldwide: Standard Int'l Delivery, Expedited Int'l Delivery
Of course, I use Canada Post and not any courier due to the lightweight packages we send.
