cost of shipping worth the effort?

Because of distance (Calif. to Ohio) I think for me it would be more cost effective to ship a 600 pound + pallet. Rather than shipping many 70 pound boxes more frequently. I think even if it was just once a year. Am I wrong? Has any one worked out the cost difference between many boxes and a single pallet? When you consider time, distance and efficiency factor, has me convinced that a pallet would be best for me! Would like the feedback, as most of you have way more experience with e-waste. To everetswift thanks for the post and not trying to hijack your thread, hopefully just add to it.
