How Much Is Next-Day Shipping US to Canada?

I looked at USPS for their International Express Plus option (one to three days delivery), but they don't show the prices for some reason. On USPS' site it has the option to "Calculate Shipping Cost" and makes you fill out all of the information for the initial place and the destination, and when you go to hit submit or whatever it sends you back to the page saying you need to fill in all the required fields first. Well I reviewed and reviewed what I filled in and I definitely didn't exclude anything so I do not know what the site's going on about. Does anyone know the rates? It's only from Bangor Maine to Dartmouth NS. I have things shipped to a hotel I stay in in Bangor whenever I shop there and they ship it to me(things that cannot be delivered to Canada from some Ebay sellers etc.). It's about a six hour drive to the border so...Anyways, this time I need the hotel to ship it in one or two days. I'm looking to see my options on which shipping company has the fastest and cheapest carrier who will get me these things before Christmas. They should be arriving at the hotel around the twentieth.

Thanks in advance...And yes, I probably could ask my family, being most of them work for the post office, but it's late and I was just trying to figure this out for tonight. I work all day during the day and don't have much time to price shop.
