Black Friday 2026 in Brazil: Date and Coupons That Work

When is Black Friday 2026 in Brazil?

Black Friday 2026 in Brazil is on Friday, 27 November ^[1][6]. The date follows the United States calendar: it is the day after US Thanksgiving, which in 2026 falls on Thursday, 26 November ^[6].

Each store sets its own campaign, and many start weeks earlier and finish later: Mercado Livre's, for example, starts on 19 October ^[1][2]. Cyber Monday falls on Monday, 30 November ^[2].

In practice, the Black Friday 'day' has turned into a season. Early offers, double dates such as 11.11 and flash sales appear in the weeks around it ^[2][8]. The best approach is therefore to decide what to buy in advance and follow the price of those products through the season, rather than reacting to the advert of the day.

When does Mercado Livre's Black Friday start in 2026?

According to Canaltech, Mercado Livre's official Black Friday campaign in 2026 runs from 19 October to 30 November, with offers marked by the Black Friday tag ^[2].

Mercado Livre's own Black Friday page confirms 27 November as the main date and warns that "campaign dates and the validity of each offer may vary" ^[1].

In October, the company announced more than R$100 million in coupons for 11.11 and Black Friday, along with 37 million listings on promotion and three times as many offers above 70% off as the previous year ^[3][8]. These figures come from the company itself and describe the campaign's total volume, not a discount guaranteed to each customer.

According to A Tarde (28 October), the Mercado Pago credit card allows up to 21 interest-free instalments on various products, extended to up to 24 from 11 November ^[8]. Interest-free instalments are not a discount: always compare the final cash price with the instalment price.

How do you find Mercado Livre coupons that actually work?

Mercado Livre's official coupons appear in its own app and website, and the company says new coupons will be released every day during the campaign ^[3]. A coupon that arrives through a third-party link must be checked on the official channel before any purchase ^[5][7]. As of 13 November, no specific coupon is guaranteed to work: coupons expire and have conditions, so read them in the app before relying on one.

Step by step:

1. Go in through the app or by typing the address. Procon Sorocaba advises against clicking links on social media directly and recommends the official app or typing the address into the browser ^[5].
2. Look for the coupons and offers area of your account. Read each coupon's conditions: minimum spend, eligible categories and expiry.
3. If a coupon has to be activated, do it before going to the basket, and check at the payment step that the discount was really applied.
4. Compare the final price. A coupon on an inflated price is still expensive. Add shipping and interest and compare with the same model at other stores ^[1][5].
5. Confirm the offer on the store's official channel before clicking links received by email or WhatsApp. If you pay by Pix, check the amount and the recipient's details ^[5][7].

Flash offers can last up to 12 hours, and daily offers up to 24 hours or until stock runs out ^[2]. This creates pressure to decide quickly; having your shopping list and reference prices written down beforehand helps you avoid impulse buys.

Does Mercado Livre's Black Friday tag guarantee the lowest price?

No. The tag considers the listing's own price history over the previous 60 days, but it does not guarantee that the product is cheaper than at other stores ^[2].

According to E-Commerce Brasil, the Black Friday seal keeps the same rules: it only applies to items on offer at their lowest price of the last 60 days ^[3]. Mercado Livre sets and applies this rule itself; it is not an independent price check.

Two limits matter for shoppers:

• The window is short. A price that is the lowest in 60 days can still be high compared with the whole year.
• The comparison is only with the same listing. Another seller, or another store, may have the same product for less ^[2].

Use the tag as a first filter, not as proof of a good deal.

How do you check a price history and avoid 'half of double' deals?

Follow the product's price in advance: that is the advice from Brazil's consumer agencies to avoid 'metade do dobro' (half of double), when a store raises the price before the campaign to fake a discount ^[5][6].

Procon-SP's Black Friday leaflet, November 2025 edition, advises monitoring prices in advance to avoid "false promotions" ^[6]. The 2025 booklet from the National Consumer Secretariat (Senacon) calls the practice "everything at half of double" and suggests using price-history comparison tools ^[6].

How to do it:

1. List the products you actually want, with the exact model (memory, colour, voltage).
2. Note today's price and follow it on a comparison site with a price-history chart.
3. On the day of purchase, compare the final price with the lowest price you recorded.
4. Ask for the invoice (nota fiscal), and put any cancellation request in writing ^[5].

A survey points the same way, though it is not representative. In a Procon-SP survey run from 30 October to 17 November 2025, with 329 volunteer participants (a non-probability sample), 76.47% of those who bought said they had felt misled in a Black Friday purchase ^[6].

How can you tell if a store is trustworthy on Black Friday?

Check the CNPJ company number, physical address and customer service channels, and look up Procon-SP's 'Evite esses sites' list before typing in card details ^[5][7].

Decree 7.962 of 2013, which regulates e-commerce, requires a site to show the seller's company name and CNPJ or CPF, its physical and email address, itemised delivery costs and the delivery time ^[6].

The Procon-SP list is a public register of shops and digital profiles with a record of problems with consumers, kept on Procon-SP's site; Olhar Digital notes that absence from the list does not mean the supplier is reputable ^[7]. So combine the check with other precautions:

• Be wary of prices far below the market ^[7].
• Prefer stores with a presence in Brazil: Procon Sorocaba notes that the CDC does not apply if the site has no representatives in the country ^[5].
• When paying by Pix, check the amount and the recipient's details ^[5].
• Insurance and extended warranties are optional and cannot be imposed ^[5].

Can you return a Black Friday purchase in Brazil?

Yes. For purchases made outside a physical store, such as online, the consumer can withdraw within 7 days of signing the contract or receiving the product, and gets the money back ^[4][5].

Article 49 of the Consumer Defence Code says the consumer may withdraw from the contract within 7 days of signing it or of receiving the product or service when the purchase happens outside the business premises, and that amounts paid will be returned immediately, adjusted for inflation ^[4]. Procon Sorocaba gives internet, WhatsApp and telephone purchases as examples ^[5].

If the store fails to honour the offer, Article 35 lets the consumer choose between demanding fulfilment, accepting an equivalent product or cancelling with a refund of what was paid ^[4]. This covers late delivery and a product different from the one advertised ^[5].

If the company does not solve the problem, you can complain to your city's Procon or on consumidor.gov.br, where the company has up to 10 days to respond ^[6].
