I agree.

If I am selling an inexpensive cel I just ship it,
but if the cel is very nice or fairly expensive I 
usually insure the package to be safe and 
consider the cost part of the cel payment and 
shipping cost.  I just feel better about it and 
it usually is not very expensive.  I ship 
Priority Mail and I believe 
(may be wrong, maybe it is more cost?) 
they include insurance up to a certain amount if 
you ask for it.
