Thank you, Cobwebs for bringing this oddity to my attention.
OK, folks, I find this tres weird: Costco sells coffins. I'm supposing this is cheap and convenient for those do-it-yourselfers out there who are trying to save a buck by pulling together their own funeral. Then again, maybe this is for the small business person who does a few funerals a year, in addition to running the town gas station and car wash. If one did a significant number of funerals, I'm sure you could get a better deal through a coffin distributer, right?
What's extra special creepy is they also sell cremation urns. I'm guessing this is for the bereaved to bring to the crematorium, and not to have on hand after a backyard do-it-yourself bbq.
What I really want to know is: What? No headstones?
