Japanese Catalog or the Mark of the Beast?

There's a Japanese e-commerce website at http://www.666-666.jp/. I saw an advertisement for it on TV in a restaurant in Akita. I didn't write it down or make any special effort to remember it, but 2 weeks later, I still do.

It's easy to remember but you would never see such a number in the U.S. for a a general e-commerce site or even a phone number because 666 is associated with the Beast. The site would get lots of hits but even more protests.

Funny how things differ from country to country.
