Costco Coffins

Christopher and I went to Costco today, and as we were leaving the store, we noticed a kiosk of different coffin styles for sale.

Now, for some reason, I was already privy to the fact that Costco sells coffins online, but I wasn't aware that you could also order them through the store.

Why would you buy a coffin at Costco?

Does one wake up one day and say, "Let's see, I need toothpaste, Pine Sol, and oh yeah, a coffin".

Isn't a coffin one of those things that you can't necessarily plan on?

Or, do you think you should buy one, and store it in the basement until it's needed?

...and if you buy it from Costco, do you need to buy it in a set of 6?
