We got a tip from I4U Reader Todd, that Costco (large membership based US retailer) has the Robosapien Toy Robot for just $69 in their stores. I cannot confirm this as the robot is not listed on their site yet.
$69 is about $20 less than the cheapest online store offers. Amazon.com still sells the Robosapien for $99.
I ordered mine from ComputerGeeks for $89.99, because the have a low-cost (albeit slow) international shipping option.
