Although I believe there is going to be distributors,situated so as to be able to supply a casket quickly thru out the United States.You can also like anything else have a casket shipped overnight.
This is going to be another source of income for funeral directors.I know with my mom and dad,they took me to a lower level where they had about 10 different caskets,in style as well as price.It is to the benefit of the funeral home to have one of each product available to view.When it comes to the Urns,you do not get them right away,it takes a few days,so they shouldn't be a problem.
