I have a private buyer & it’s packed in a 26" x 20" x 16" box. What’s the cheapest way to ship it? USPS, UPS, FedEx?
Fedex is cheapest if shipping anywhere in the U.S. You would have to check a shipping quote for each company otherwise. I’m not sure about international shipping.
Your buyer may prefer USPS. I don’t have any insider information, but my packages from FedEx and UPS tend to get dinged duty at the border (up to 50% of the value of the item!) much more often than any package from USPS. For expensive items its often worth paying more for shipping compared to paying the duty!
I have had great luck with UPS shipping to and from Canada
