Unless..... You didn't try to get the shipping costs on an uncut 4x8foot sheet, did you? UPS has a max size. You have to get a full sheet cut down to smaller than the UPS max. If you call them, they can tell you what the max shipping dimensions are. I seem to recall them being able to do 4' by 32", basically cutting the sheet in thirds. You might want it cut differnetly depending on how you want your flutes to run in your wing. If you can't figure it out on the website, call them on the phone, their sales folks are really helpful and friendly and last I checked, they actually know about people using the stuff for airplanes.
