well, fedex fright estimate to seattle is $1018.67 Not sure if i did it right and I just guessed on the weight, but it was the same for 75 lbs and 150 lbs. The only other option would be to dismantle it...
If i were to take the runners off and the legs off and put the legs and runners in one box and put the frames in another with estimated weight i get a shipping cost of about 80 bucks to go to seattle. Oh yea plus the tubs would be a 3rd box and they were shipped to me for 20 bucks i think. so about 100 to ship it i guess. for 250 bucks you could build one yourself...
