Black Friday wine deals: is the discount real?
Sometimes it is, sometimes it isn’t. The way to know is to compare the advertised price with the full price from before, not with the “was” price the store writes. The house checked, at large Brazilian stores, the full-price range of the wines in the search that have one: pick the wine, type the advertised price and it tells you whether it’s below, within or above what the house saw. Right after, what to look for in the ad, with the signs that Senacon and the Procons (Brazil’s consumer protection agencies) describe, and what Brazilian law guarantees.
House tool in the barrel point out a mistake and the house learns
Does the ad match the house’s range?
Pick the wine from the list and type the advertised price of the 750 ml bottle, without shipping.
The answer shows up here: below, within or above the full price the house saw.
- Ranges checked by the house on November 12, 2026; a wine that was not on sale keeps the date of the previous check.
- It’s the full-price range, not an offer: what counts is the store’s price and terms on the day.
- Prices change every week; that’s why the house shows the range, not the price.
- The house read the stores’ public pages one by one, without copying any catalog.
- What’s written here about the law is information, not legal advice: for your case, the Procon (Brazil’s consumer protection agency) in your city.
Without JavaScript the check doesn’t run: the table of all wines with a range is further down, under “What the house checked”.
The math without picking a wine
What to look for in the ad
In 2026, Black Friday is on November 27, and the Procon of Espírito Santo advises starting to follow prices now. The first three signs below come from Senacon and the Procons (Brazil’s consumer protection agencies), with the source; the other three the house adds, because of the wine. The house points at no store, and they hold for any year.
- The inflated “was” price. Senacon, from Brazil’s federal government, warns that some stores raise the price days before Black Friday so the discount looks big; the government calls it the “double of half” offer. The math: “was R$ 200, now R$ 120” is 40% only if R$ 200 was the real price; if the wine sold for R$ 130 in the days before, the real discount is 7.7%. What to do: compare with the price from before, never with the “was” price. The tool right above does that with the range the house checked; Brazilian price comparison sites show the history (Zoom and Buscapé, for the last 40 days or six months), and the Procon of Paraná advises looking at what the product cost three months, six months or a year ago.
- Shipping that shows up at the end. A site that sells online has to show shipping in the price, and Senacon advises distrusting a store that only shows shipping at the last step. Free shipping “over X” only pays off if the extra bottle costs less than the shipping and you’ll drink it: R$ 40 short of free shipping and shipping is R$ 25? Buying R$ 40 more “saves” R$ 25 by spending R$ 40. What to do: compare the total, shipping included, before paying.
- The store you don’t know. Senacon advises checking that the store’s CNPJ (its Brazilian company registration) is active and distrusting a store with no physical address or with a price far below the market average; the Procon of São Paulo keeps an “Avoid these sites” list. Senacon also recommends favoring a credit card, which lets you dispute an improper charge, and says Pix, boleto and bank transfer make a refund harder in case of fraud. What to do: at a store you don’t know, with the wine far below the house’s range, check the CNPJ first.
And the three the house adds, because of the wine:
- The price per liter read as the “was” price. A store that shows the liter price next to the bottle price puts two numbers on the screen, and the bigger one may be the liter’s. A 750 ml bottle costs three quarters of the liter price: R$ 80 a liter is R$ 60 a bottle. What to do: look at what’s written next to the number (“/L”, “per liter”) before assuming it’s the price from before.
- The bundle. “Buy 6, get 7” is a discount of 1/7 per bottle, 14.3%, not 1/6: six bottles at R$ 70, R$ 420, for seven bottles, come to R$ 60 each. The bundle is allowed. What Brazilian law forbids is tying sales: you have the right to buy a single bottle without taking anything else (CDC, art. 39, I). What to do: divide the total by the number of bottles and compare with the price of one. It’s only worth it if you’ll drink the seventh.
- The old vintage of white and rosé. Well stored, an everyday white keeps its quality about three years after bottling (Purdue University), and almost all Australian wine, for example, is made to drink young (Wine Australia). Rosé from an earlier vintage isn’t spoiled rosé: in Provence, says the region’s wine body, rosés with two or three years in bottle can even shine again. In Brazil, the vintage on the label is optional. What to do: a big discount on an everyday white or rosé from an old vintage calls for a look at the vintage in the photo; if the ad doesn’t say, ask before paying.
What the law guarantees
This is Brazilian law, for purchases made in Brazil. The house tells you what the law says: it’s information, not legal advice; for your case, the Procon (Brazil’s consumer protection agency) in your city.
- The ad is binding. A precise ad, with the price, binds the store and becomes part of the contract (Consumer Protection Code, art. 30). If the store doesn’t honor the advertised price, deadline or terms, you can demand what was advertised, accept an equivalent product or cancel the purchase with your money back, adjusted (art. 35).
- The advertised price has to be correct. The law forbids advertising that, even in part, misleads about the price (CDC, art. 37), and a false or misleading statement about price is a crime under the CDC (art. 66). No Brazilian federal law defines the “previous price” of a sale: Senacon says that raising the price beforehand so the discount looks bigger goes against the Consumer Protection Code, which forbids misleading advertising (art. 37). In 2025, the Procon of São Paulo recommended that the companies with the most complaints apply the discount to the lowest price of the last 60 days, and that’s a recommendation, not law. In the European Union it is law: the previous price is the lowest the store charged over a period of at least 30 days before the discount.
- Two prices for the same wine in the same store: the lower one counts. If the product shows different prices in the same store (the shelf tag and the checkout, the page and the cart), the consumer pays the lower one (Law 10,962/2004, art. 5). And online, the cash price has to stand out next to the product image; for installments, also the total, the installments and the interest.
- Seven days to change your mind. When buying online or by phone, you can withdraw within 7 days without giving a reason (CDC, art. 49), and Senacon counts from when you receive the product. Everything paid comes back right away, adjusted; Brazil’s Superior Court of Justice (STJ) ruled that return shipping is on the store, and Senacon says the refund includes shipping both ways.
- The delivery deadline is part of the offer. The site has to state the deadline, and leaving the date solely up to the store is an abusive practice (Decree 7,962/2013 and CDC, art. 39). If it’s late, the same art. 35 applies.
- Where to complain. On Consumidor.gov.br, Senacon’s public platform, where the company has up to 10 days to answer, or at your state’s Procon.
- 18 years old. Selling or delivering alcohol to anyone under 18 is a crime in Brazil (ECA, art. 243).
Wine has its quirks
Delivery. Wine’s biggest risk is heat: above 24 °C it changes aroma, flavor and color, and in delivery it shouldn’t go past 30 °C even briefly, according to Purdue University. The damage often only shows when the bottle is opened; from the outside, the signs are wine seeping past the cork and a stained label. On a hot day, take it in right away and store the bottle lying down, out of the sun, between 10 and 16 °C if you’ll keep it a long time. Sparkling wine that traveled a lot needs a few days of rest before opening, recommends the Comité Champagne.
Age. Well stored, an everyday red holds for 3 to 10 years after bottling and a white for about three; and some wine is made to drink in its first year (Purdue University). In Port, only Vintage ages in the bottle; most LBVs are ready to drink when bought, says the Port wine institute.
The bottle. Size changes the math: R$ 35 for a 375 ml half bottle is R$ 93.33 a liter, more than R$ 60 for a 750 ml bottle (R$ 80 a liter). A 3-liter bag-in-box lasts four to six weeks after opening, because the bag collapses and lets no air in; in Portugal, according to the consumer association there, the liter costs up to 50% less than in a bottle. It’s wine to drink young. The per-liter math is in the tool, up top.
And the Christmas gift?
Black Friday is a month before Christmas: if you’re buying the gift wine now, check the delivery deadline on the page before paying. In São Paulo, state law requires stores operating there to offer a delivery date and time slot at no extra cost; the Procon of São Paulo advises requiring the delivery date and shipping cost on the order.
Which wine to give? Gift a Wine asks who it’s for, how much they know about wine and how much you want to spend, and picks from the wines with a checked range.
Pick the gift wine →What the house checked
Each wine’s range comes from a check done by hand, and the house says how:
- Only large Brazilian stores: supermarkets, wine-shop chains and the producer’s own store when only it sells the wine; never a marketplace. Stores from the same group count as one.
- Only the product page, for the 750 ml bottle, in stock and sold by the store itself. The full price counts, without promotions; if stores disagree, the site shows the higher range, and the lower one is kept for the tool up top.
- The liter test, on every page that shows the price per liter: the house checks that the number is the bottle’s and not the liter’s.
- A “was” price more than 15% above the reference full price doesn’t decide the range: it’s recorded, only in aggregate.
Where the house looked: Angeloni, Carrefour, Decanter, Divvino, Extra, Mistral, Pão de Açúcar, Sam's Club, Savegnago, Sonda, St Marche, Super Muffato, Super Nosso, Vinci, World Wine, Zaffari, Zona Sul. That is 17 large stores, from 14 groups (Angeloni and Divvino, Carrefour and Sam's Club, Extra and Pão de Açúcar belong to the same group). No store pays to be here, and none reviewed or approved these ranges. The house sells no wine and, today, earns no commission from any store.
The caveats about these ranges are next to the tool: read them.
In November 2026, the house looked up 232 wines: the 188 that already had a range and 44 new candidates. That was 560 lookups in 17 large stores, from 14 groups, and in 10 winery shops, for the wines only the winery sells. 157 wines stayed in the same range, 6 went up and 4 went down. 21 were not on sale in any large store this time, or were sold out: they keep the range and date from the previous check. Of the new candidates, 4 got a range and 40 were left out this time.
For 24 wines, large stores charge full prices that fall into two ranges. The wine page shows the higher one; the tool above uses both, so it does not call another store's regular price a discount.
See all the wines checked
In alphabetical order. The range is for the 750 ml bottle, at full price, with no promotion and no shipping; the month is that of each wine's latest check.
On the pages it read, the house saw 87 promotions on 74 wines. In 46 of them (on 39 wines), the “was” price was more than 15% above the full price the house had as a reference.
This is not an accusation against any store: a promotion's reference price may be what that store itself charged before, and prices change. It is simply why the house compares with the full price of more than one store.
Are you a store or a winery? Correct or remove a price
The range is wrong, the official full price is different, or your store or your wine doesn’t want to appear in the house’s checks: tell us here. The house confirms through the company email and answers within 1 business day. Brands and names appear only to identify the wine; what counts is the store’s price on the day (Terms of use, item 9).
