Know where everyone's will is located. Know what their wishes are beforehand (cremation, funeral, burial, etc). If they have a DNR, keep it somewhere readily available incase you need it. If you can't find it, it doesn't exist.

If you're getting a headstone in spring, be prepared to wait. It's a busy time of the year for that industry.

Saving money after a loved ones death doesn't mean you loved them less. Death is expensive, save where you can. For example, don't buy an urn from the funeral home, they're 10x the cost.
