You might be looking at discontinued items which haven't been removed yet, because that item was discontinued. When searching for items sort by Latest Arrivals. It's easier to find current items on Sears.com or Kmart.com. Search for items select Sears Only for items sold by Sears. You'll be able to redeem points in checkout.
