Side note: I am not sure how I feel about these techniques. I remember something similar on hobbyking, where if you left a page open for too long a pop up would come up offering you a discount for the item. Once I figured out it did this, I would go around leaving pages open hoping to get discounts. It was annoying, and I would refuse to pay full price after I saw this in action, even when it stopped making me offers. Be careful when overly gaming your customers.
