I shipped both of the seats for around $60.00 total. The 60% seat went ina box that was 25" x25" x 34" and the drivers seat went in a box that was 25" x25" x 28". They do not care how big the box is if you are transporting by ground. MOst of the shipping companys charge the high rates for anything that takes up space in an aircraft. UPS and FED-EX wanted to charge me an arm and a leg....I told them to pack sand and went with DHL...set up an account on the internet, they sent a package of pre-paid waybills and package material the next day and that was it. The seats went out on Friday and one is already in Jacksonville and the other will be there before the day is out and they will be delivered to partsman on Monday.
