Containers are different of course but if you are looking to move a lot of stuff then you should use pallets as they are done by size not always weight. I think but dont quote me on this that 2 dollars a pound is up to 80 lbs. Believe me on this as over the last 2 years I have sent or had sent over 100 boxes of stuff...... Oh yeah Fed Ex and UPS are about 4 times as much as the US Postal Service. .........I sent over a canoe yes a canoe that weighed 38 pounds and it cost me just under 100 dollars, the extra was because it was over a size limit, either way a little more than you were paying. Fed Ex wanted 380 dollars and UPS wanted 420, I went with the Post Office...... Last example, I sent over my truckmount with loads of other stuff, 300 feet of 2 inch hose 300 feet of 3/8 solution hose, lances, wands, sprayers and like i said loads of stuff, cant remember what it all weighed but close to 1800 pounds I am sure.... It cost me 960 dollars..... and that was it being flown here to LHR not by an actual ship........Hope this helps, best, Dave.
