I work in claims & customer relations for a Winnipeg-based United Van Lines member. I acknowledge that van line rates are usually more expensive than U-Haul or the fly-by-nighters out there. Let me give you a couple pieces of advice.
1 - You can use car carriers (the kind that deliver new cars to dealers) to ship your car for you. Delivery can often take a week or two or more, depending on location and proximity to a major city (obviously not a problem for you!), but it would mean a single trip across the border for you.
2 - If you're looking at just
shipping a few boxes and smaller items, you may want to look into bus mail options. I'm not sure if they can go across a border, but I know that I recommend bus mail to lots of folks within Canada who contact us for quotes on small shipments. It's relatively inexpensive and much quicker and safer than, say, UPS Ground.
3 - The key thing you need to ask yourself is how would you define a
good move? Is it more important for you to save money, or more important to keep your things intact? My experience is that you usually can't have one without the other. Sometimes the stuff people ship is junk and they don't care about nicks and dings, and that's totally cool, as long as you know you run that risk if you are looking to save some coin. And from my personal experience, I agree with Reba - claims resolution is much easier for the consumer when you ship with a van line. I used to work for FedEx so I know both angles somewhat well.
4 - When considering a mover, get a referral from somebody you know. Little known fact: most van line agents can arrange a move from anywhere to anywhere. Were you so inclined, I could even set you up with one of the sales reps in our Winnipeg office to book the move. That works because we would use trusted van line members at the pickup & delivery ends of your move, and we'd oversee things from our office to make sure the proper follow-ups are in place etc. But this isn't a sales pitch; you don't know me from Adam and shouldn't trust me without a referral. Talk to people; find somebody who has a glowing recommendation for a van line mover in any city and see if that mover can arrange your move. Sounds crazy, I know, but it works.
Hope this helps.
