I live in Oshawa and I had my Songbirds delivered by freight truck in 2012. I think it added about $400 to the cost of the speakers in the end. This was when the dollar was at or close to par. Those Song 3's are also quite a bit heavier than the Songbirds. If I was to buy Salks again, I would probably just pick them up myself. Given the circumstances we are in now, taking the drive to Windsor sounds like a good idea.
