Nooooooo (As I make a overdramatic leap toward the 
poor helpless cels)  Pay the shipping have them sent  
using very stiff card board or even the cheap brown 
press board you can get at Home Depot they even cut 
the sheet to the right size.  I sent a 4 ft framed cel that 
way, and shipping was still only 10 bucks the board 
was 5.  Rollong the cels is aking for cracked paint, 
tearing, and warping.  Imagine the paint sticking to itself 
on a hot loading dock.   I shutter.....    (is that dramatic 
enough?)  Really you will be much happier.
