I have seen some people down on the Boardwalk in Virginia Beach on these- they are very cool to watch!
The great thing about Woot is that if you pay the $5 shipping (which is included in the price above) you can throw in as many other items as you like from Woot and the shipping is covered.
So you can also check out:
Woot Tech 
Woot Home 
Woot Kids 
Woot Shirt 
Generally their deals only last one day (or while supplies last) so be sure to check them out today!
