When is Black Friday 2026?

Black Friday is the day after US Thanksgiving — Friday 27 November 2026 — with many stores starting earlier and running into Cyber Monday (30 November). In the Gulf it’s often called White Friday.

7 red flags

  1. A suddenly inflated “was” price: check what it cost a few weeks ago.
  2. Cheaper elsewhere without a deal: compare at least two stores.
  3. Big discount on an old model: check the model number and release year.
  4. A countdown that keeps resetting: pressure, not a real deadline.
  5. Shipping or fees eat the saving: compare the final price.
  6. Shorter return windows on sale items: read them before paying.
  7. Stacked discounts don’t add up: 20% then 10% is 28% off, not 30%.

Do the maths

Sale price = price × (1 − discount ÷ 100)

Example: a $500 TV at 15% off → 500 × 0.85 = $425 (you save $75). With an extra 10% coupon → 425 × 0.9 = $382.50, which is 23.5% off in total, not 25%.
