For us canadians, the worst of them all is UPS. We get charged monstruous courting fees. For examble : I recently ordered for 95$ USD of stuff. Paid shipping with UPS of 35$ USD to get it shipped to me and then SURPRISE a 50$ CAD COD. That's half the value of what I bought. I emailed them a couple of times regarding this, but all I got of of them is pay your COD or you don't get your stuff. So now, whenever I can choose USPS or other regular postal services I do.
