Burial life insurance is usually used to pay for immediate medical expenses related to funeral, credit cards, etc. Features of burial insurance include:
Small face value policies
Easy to qualify for (yes / no application)
Can accumulates cash value (most don't)
Life insurance premiums remain level
Provides insurance protection to age 100

Reasons to buy burial or graded life insurance:

You don't want your loved ones left with any of your debts from a funeral, credit cards, etc.

You will show your loved ones that you care now by providing for them later.
