Cheaper? I didn't know it was cheaper.
I don't care how much a burial costs. I will go with a burial any day.
What if someone kills and you are cremated? That will get rid of all the evidence, and there really won't be a case. Consider a burial. It will be better for you in case someone kills you, but you won't know if someone's going to kill you, so just go with a burial to be on the safe side. Even if you think no one wants to kill you, you never know these days.
