My guess is you'll see the leftovers in London next year.i don't know what happened the next four hours after i left but it would not "shock" me if most stuff did get bought out by people either waiting to go after the line were done or wanted to make some extra money.
As for the Salacious Crumb clock, I'm pretty happy I decided to buy one because it's pretty cool. Be careful though because the mechanism in the back that makes the eyes and tail move is long and thin and probably very easy to break. Also, the clock hands are not protected in any way and could be easily broken by rough handling. That said, they did a great job of packaging them - I brought mine home in my checked suitcase and it made it through two flights and the associated baggage abuse in perfect condition, and worked as soon as I popped the battery in.
