We had heard about $15,000 for funerals including visitations, coffin, service and burial. Tombstones are ridiculous in price. You are right about the death certificates. I think that I needed about 10 for DH and was given 12. A new minimalist provider just started up in the last year with reportedly cheaper rates. I have not checked them out.
We have a problem now with too many funeral homes and few historical funerals that pay substantial revenue. One has closed and I expect more will as time goes by.
