Those of you who ship internationally, what is your preferred and most reliable shipping method out of the USA? Small shipments, just a few boxes.
We primarily ship UPS. We have shipped to Canada several times with UPS, it usually gets to where it needs to, but often gets delayed in customs. I have a customer that has a firm delivery date to London and it's coming up quick and I'm skeptical to commit since I never know whats going to happen in customs.
