Follow-up: Zappos was super great about the issue and gave me credit for the damage from improper packing in the shipping box & missing baseplates; so we bought more cases (without the workstation frame).
Update: Apparently Zappos doesn't stock them any more, but they still have other LEGO items here: LEGO Lifestyle items at Zappos
As of November 2011, IRIS storage set is available at these places: Target -- as well as Amazon
and at Toys'R'Us
