Not content to put the mom and pop stores out of business, the Bentonville, Ark., behemoth now wants to bury funeral homes. This is not some kind of zany Halloween marketing hoax -- at least that we know of. Wal-Mart, the world's largest retailer, is now selling ... discount coffins. In the "For the Home" (?) area on the Wal-Mart website, feast your eyes on its entire line of inexpensive caskets and even urns, for all of your bereavement needs.The prices of the Wal-Mart caskets are to die for. All but one of the coffins sells for under $2,000. The deluxeSienna Bronze model sells for a still bargain-basement -- in casket terms -- price of $2,899. One of the least expensive model is the still lovely Lady de Guadalupe Steel Casket (see above) at $895. Another design sports a carving of "The Last Supper" by Leonardo da Vinci.
