Sears Holdings, the parent company of both Sears and Kmart, has put its media buying and planning duties up for review, reports AdAge.
The review comes as the company looks to "improve efficiencies" at both retail outlets. WPP Group's MindShare and MEC Interaction currently handle those duties, having previously worked on Sears's account and then Kmart's after Sears Holdings consolidated duties last year.

Both agencies have been invited to participate in the review, with a decision expected in the second quarter of this year. TNS Media Intelligence estimates Sears Holdings spent $780 million on advertising in 2006.
