Staff at a branch of Asda in Manchester were forced to call police after bargain-hunters brawled in the discount section.
The police say two shoppers began arguing over the products with yellow reduced stickers on Sunday (February 4).
Others in the shop watched as the argument escalated just before closing time, according to The Mirror.
One of the men was left with minor injuries as a result of the fight, but reports suggest officers did not make any arrests.
The GMP Trafford South Facebook page has criticised the "red-faced" men for wasting officers' time.
The post read: “Waste of police time award goes to several patrons at a local supermarket."
Skirmishers were also criticised for wasting public funds, and customers were told "don’t fight over a 10p sandwich when trying to save some dough.”
Anyone with information about the brawl is asked to contact police on 101 with incident number 1474 or Crimestoppers anonymously on 0800 555 111.
