Since Sears owns KMart can you return an item you brought at Sears to KMart? or vice versa?
No. Kmart and Sears stores still operate independently, therefore products shipped from Sears store or Sears.com must be returned to a Sears store. That's the same for those products purchased or shipped from Kmart stores or Kmart.com, they must be returned to a Kmart store.
Kmart and Sears completed the merger in 2005 and they became wholly-owned subsidiaries of Holdings, Sears Holdings Corporation - a leading integrated retailer focused on seamlessly connecting the digital and physical shopping experiences to serve our members - wherever, whenever and however they want to shop.
