Retail sales fall as Black Friday deals fail to lure shoppers

November retail sales unexpectedly fall as Black Friday discounts fail to lure shoppers, with supermarket sales declining for the fourth consecutive month. Despite hopes for a 0.4% increase, sales volumes actually dropped by 0.1%. However, recent months have seen growth in computer, clothing, and furniture purchases. Meanwhile, the GfK consumer confidence survey indicates a positive outlook for household finances, although concerns remain.
