In the case of a rental coffin (they tend to exist), you pay for the rental fee, and the liner. Someone else can speak toward liner fees, but I’d take a guess that the two fees together would still reach $750 minimum.
I remember when my German father-in-law passed on...the gal pulled out the catalog and I was surprised at the simplicity and cheap level you could go. You could have gone for a cardboard situation, and with no bells and whistles, maybe spent $500. After that, their five-star deal and best situation was around $20,000.
I have always thought that funerals etc. are for the living. The dead really don’t care. It’s just me but I don’t see the benefit of display for visitation or embalming. I also don’t like long drawn out funerals. I think it all just makes it harder for the family.
So when both my parents passed we went as simple and inexpensive as possible. Used the heavy cardboard caskets for both. They were beautiful and no one knew the difference. Total funeral costs which included lots of flowers was around $3200. They were in an ‘outdoor chapel’ at the cemetary that was provided with the plot. The grave plot and marker were separate.
Everyone thought the funeral was totally appropriate.
