I was thinking the same thing. And I even spent that last 10 minutes perusing their site. I don't know if this publicity was worth 1.6 million in the long run, but I believe it will bring in more sales than if it had not occurred. I am even tempted to pass this site along to my wife (the big shopper in our household).
Until today I had not ever heard about 6pm.com.
Due solely to their mistake, this post, and their honor, I'll be sure and check them out for future purchases.
