Black Friday 2026: How to Tell if a Discount Is Real (and Pay Less)

Black Friday 2026 falls on Friday, 27 November. It is the best time of the year to buy what you already needed — and the favourite time for inflated "was" prices. These five steps show whether a discount is real and which way of paying is cheaper.

1. Write the price down before

The surest way to spot a fake discount is to know what the product cost a few weeks earlier. Price-history tools (camelcamelcamel or Keepa for Amazon, Google Shopping's price insights) show the chart of the last months. If the crossed-out price never existed, neither does the discount. A simple alternative: at the start of November save the links and prices of what you want, then compare on the day.

2. Compare the final price, not the percentage

Add shipping, any pre-ticked extended warranty and fees. A 40% discount with expensive shipping can cost more than 25% with free delivery. Always compare the total in the cart.

3. Pay now or in "interest-free" instalments?

When a shop gives a discount for paying up front, the "interest-free" instalment plan hides interest: the gap between the two prices. A product of 1,000 in 10 monthly payments of 100 (first in 30 days):

Up-front discountUp-front priceInterest hidden in the instalments
5%950about 0.94% a month (11.9% a year)
10%900about 1.96% a month (26.3% a year)

The rule: if your savings earn less per month than the hidden interest, pay up front. The cash or instalments calculator does it with your price, number of payments and the rate your money earns.

4. Avoid scams

  • Type the shop's address yourself or use its official app; don't buy from links in messages or ads with prices too good to be true.
  • With unknown shops, pay by credit card (or a virtual card) so you can dispute the charge.
  • Keep a screenshot of the offer with its price and conditions.

5. Know your rights

Return and cancellation rights depend on your country — for example, in Brazil online purchases can be cancelled within 7 days of delivery (Consumer Code, art. 49), and in the EU within 14 days. Check the shop's return policy before paying.

Educational content. The hidden interest in the examples assumes 10 equal monthly payments with the first one in 30 days.
