It's getting easier to shop prices on the one big expense many people put off planning — their own funeral.

Costs for those final arrangements can vary widely. An October survey from the Funeral Consumers Alliance and the Consumer Federation of America found full-service funeral prices ranging from $2,580 to $13,800. Even within the same city, the groups said, highs and lows often had variances of more than 200 percent. (See chart below for pricing.)
