By some odd turn of events, Grand Union carried the Grand Union brand of margarine. Was anyone's margarine ever less than 100%?

More wiki history. This makes my head hurt:

C&S was owed huge money by Grand Union so they repossessed the entire Grand Union chain, bringing it out of bankruptcy and immediately began working to consolidate Grand Union's operations after making a stalking horse offer. This involved exiting the New York metropolitan area market, where it had done the core of its business, altogether. Most of the larger stores and a decent amount of construction permits were sold to Ahold . . .

The rest that weren't sold to competing supermarket or drugstore chains were converted for other retail use or (at least in the case of the former flagship store in Elmwood Park, New Jersey, where the original corporate headquarters was located and where the office tower attached still stood) demolished and replaced with other buildings.
