Not sure about Amazon.ca, but .com would almost certainly ship it. Since it appears to be sold by Amazon.ca, I think they will ship it. If there is a problem, just phone and they should make it right. The price jumps is exactly what happens when you find a really good price and buy: it skyrockets!
I buy off of .com because the prices are usually better, and I can get them delivered to a receiver just across the border.
Shopping for discounts and deals on Amazon is a real time waster!
