NOTICE FOR COMPUTER WORLD (X2Gen) REBATE CUSTOMERS ONLY: Computer World (X2Gen) has filed for bankruptcy. As a result, we will not be able to process any Computer World rebate checks because we have not been provided with the necessary funds. We have been informed by the attorney for Computer World that they do expect to be able to release funds to fulfill your rebate. We do not know if and when this might occur. Please continue to check back for updates on the status of Computer World rebates.
