CompUSA just signed an agreement with the FTC (I think) that holds CompUSA (and presumably sets a precedent for other retailers in the future) responsible for rebates that they advertise, even if they are offered by the manufacturer. Apparently, a mfgr offered a rebate that was advertised by CompUSA, then the mfgr went out of business. CompUSA agreed to be liable under the terms of the settlement. It was in the Washington Post this past weekend.
