Never, ever, use UPS or Fedex or DHL for cross border shipments, unless you absolutely have to, they charge a min brokerage fee, then a percentage of value on top. Can't speak to USPS as to what they chg, but from US to Cda via USPS/Cda Post is only 10.00 for brokerage, then they charge GST or duty if applicable, which the duty usually isn't, at least on small stuff. They missed 6 of 8 boxes of made in China decoys out of the US, dinged me 14.00/box on two of them. They miss GST most of the time too. I heard there is a crackdown happening in CBSA/Cda Post about not collecting GST, we'll see, have one coming from Brownell's this month, maybe, if it ever clears customs ( pretty sure CBSA has had an "inspect Brownell's" order on them for a few yrs now). Then next month hopefully a stock, which is made in Norway, from EuroOptics, we'll see what happens on that one, waiting for export permit from Commerce, be a month on Boxing day.
