Cheapest Screamin Serpent Kit?

Does anybody know the site with the cheapest price of the Screamin' Serpent K'nex Coaster set?

The cheapest I've seen it is 78.80

-----------------

I saw it on ebay for $69, but that's without postage, and if peopel bid on it, it goes up more.

i saw it for $79, i think at toys-r-us.

Well, as I post this it is 9:26 Pm. Meijer has it on sale until midnight for $69.99. So get it while you can
