Yes, they had a pre-pay special at the funeral home. I know it sounds funny. I locked in a decent prices and made it clear to family that they should not feel pressure to upgrade when the time comes. I walked past all the expensive coffins and pointed at the cheapest one in the corner. They said you mean the large screen tv cardboard box?. Sorry, but seriously I picked the most basic wooden box. It only gets seen for a few hours anyways. I opted for a small graveside service with only close family and friends. Also I left extra money with instructions to get a nice bottle of scotch and have a small party in my honor.(I am too cheap to throw one while I am alive)
They don't let you buy the gravestone upfront, but was told that If any money is leftover from the pre-pay amount it will go towards that otherwise the government has a $2500 survivor payment that will cover it. On a related topic have your will updated and power of attorney, medical directives, executor, and service type you want.
If it was legal personally I would like to go out like the Vikings just set me on fire and push me off into lake Ontario. Then the surviving family chooses weapons to fight over my belongings and investments.
