Sounds to me like one possibility is that a freight order costs about 120 bucks. And doesn't cost significantly more if the order is larger. So he wound up paying the same price for one plane as for two.
Here again I really fail to see the problem... the shipping from 3dhs, EF, or many companies on a 50cc bird is 100-150 depending on the company. So in this case the biggest thing is that the 35cc/74-78" planes cost in the same class as a 50cc plane. In Ken's case I would just be ecstatic that I was lucky enough to get two planes for 120 bucks. I long ago accepted the cost of shipping a 35cc/74-78" plane. Doesn't make me happy, but I very much DO believe that EF is merely passing along the costs that they incur to ship these. So to me, in my way of looking at it, Ken got an incredible deal on getting the two planes shipped.
Now - one possible thing that EF could do to reduce shipping costs is to split a 35cc plane up into two boxes, then perhaps the fuse box would be smaller, and not put it up into the large UPS category, and then the other box would be even smaller, so perhaps both boxes could be shipped for under 100 bucks then. However then they pay for two boxes/plane, and I'm sure it would take up more room on the container as well. So in the end, although it may save the end user more money, it may wind up costing them more to do that. But it may also mean that they sell more planes in this size, and that may offset... who knows.
