My beloved aunt was buried in one last year. It was nice, simple, and humble.
I don’t know what a casket should cost, but they don’t seem to be that expensive either, especially considering they are hand crafted.

I used to love going to church there when I was on the north shore. I’ll have to make a trip to check them out. Maybe get one for myself, and freak my wife out.
