The price they offer on the main website is $100 more then whats listed on the insiders deal page. I don't think this page is supposed to be available to the general public, so I think as soon as they notice a whole bunch of people buying 80 hour Tivo's for $250, instead of the $350 they should be going for, they are going to take the page down.
I ordered one of 'em via the website last week, which is supposed to arrive tomorrow, and I got a local circuit city to match the special website price, plus 10% of the difference, so I got my 2nd one for $240 ($290 with a $50 mail-in rebate). The Tivo.com website sends it with free shipping and you can avoid the sales tax, so that's the better deal. But you get instant gratification from Circuit City.
