I lived in Las Vegas for 2 years, and never went to that house. I kept forgetting. I thought I heard the owner was sick of people taking pictures, so he remodeled it. But I can't imagine the changes would have been that extensive, since that would be costly...
Why would the winner turn down a house, which he could likely sell for MORE than $75,000? Seems silly to me...
That's just their schedule. Some boxes ship in the beginning of every month, and some ship in the middle of the month. They take box orders up to a cutoff date (4/15 for Nerdblock Classic), and then they start shipping. They'll start shipping early next week. It's a slow process though, but you should have the box within 2 weeks from now. And yes, don't forget to cancel. I forgot once, and the next box I got SUCKED!!! They have really awesome boxes sometimes, but others are pure crap.
