The Co-op offers an almost identical plan to Pure Funerals, but at less cost. I have arranged and and paid for mine, so all that will happen is one phone call to local co-op funeral directors, and they do all the rest.
I have absolutely no religious believes, neither do any of my children. Really no need for anybody to be at cremation when my body goes there.
I have left some money so that my children can arrange celebration of my live at a time and venue to suit themselves. I never collected ashes for my parents, etc. cannot see the point. Told crem. just to scatter them. I hold many wonderful memories of them inside me. When I my youngest son died, I was given the ashes, never knew what to do with them.
Perhaps, for some people, the scattering of these ashes at some happy place can help them, then that is fine - for me those items were never anything to do with the person I knew and loved.
