Off and Away

Launched by former Amazon and travel industry vets, this brand new travel site slings nights at dope hotels around the world via auctions with no minimum price, leading to sweet deals on packages like two nights at the Wynn in Vegas plus dinner and tickets to a show; every bid you place (bids cost $1, and come in packs from 10 to 100) raises the price of the package just $.25, so if 100 people bid, the trip costs $25 (plus the cost of your uppings), and if 200 people bid, the price is...cosine?
