oversized items don't work that way.
we bought our topper through CW and had to do the same thing, cause ours was nearly 12' long.
it costs a lot more to have that delivered from the manufacturer. CW only stocks some smaller common sizes.
it costs them a lot more for shipping longer or uncommon sized toppers.
