I just ordered some car speakers from sounddomain.com. I live in Canada and am a little worried about the what if's. I have heard the horror stories of packages being left on the door step, and of shipping damage problems. They ship "United States Postal Service Air Parcel Post" to Canada, is this a good shipping service? I used Visa but the total was just the cost of the speakers plus shipping. When are the other costs applied such as provincial tax and brokerage fees etc, etc? Is this added on to the Visa as well? Thanks for the help. Also has anyone dealt with absolutecaraudio.com before?
