My husband wants a cardboard box.
Since I'm going to be cremated, me too.
My brother worked for some funeral place hauling bodies.
Everybody they dealt with for funerary arrangements they required to purchase a proper casket through them. No exceptions. And if you decided to be cremated, then they'd pull the body out, stuff it in a cardboard box and resell the casket.
From what I understand, the guy that ran the place had actually been forbidden by the government to have anything to do with anything related to dead people, but every time one of his operations was caught out and shut down, he'd just find some new puppet to run the next place.
