Shipping prices from Canada and within Canada have risen for parcels. The numbers are coming in similar to shipping from the USA into Canada. It appears that all items are now subject to security xRay coming and going, both on the Canadian and the USA side of the border and a particular class of mailing, again on both sides of the border. Understandably, it increases the shipping costs.
In Canada, we do not have a “Media” rate for books, nor can “Media” mail be shipped to Canada from the USA.
