if it fits is ships boxes?

have any of the US mamas used these and shipped to canada? do they cahrge the same one flat rate amount to use them to shipo to canada as they do in the us?

If it's going internationally, they charge differently. But, they do have flat rate international boxes at the Post Office.

You can use the regular flat rate boxes/envelopes for international, don't have to get a special box but they DO charge differently.

alright, ty ladies
