canadian money orders

Ok, the reason why i'm wondering is because i've been buying things off ebay, and need to send money to the U.S. Does it matter if I use a U.S money order or a Canadian money order, as long as the proper amount is enclosed?

Don't think it would make a difference, though the currency used would probably make a big difference, depending on the exchange rate of the moment.

I don't think it does, so long as the exchange rate is factored in.
