How not to be fooled on Black Friday – Finance – Tecnoblog

A few years ago, one of the main dates for Brazilian retail has been the Black Friday, when several stores offer great real promotions in their products (this is what is expected). In 2021, the event takes place on November 26th. We’ve listed some important topics on what to do so you don’t get scammed and actually find good deals to buy cheap.

1. Which stores to avoid

The first tip is very important: do not buy in stores listed by Procon-SP that had complaints registered and did not respond (or were not found), which may indicate a farce.

In the list, there are some stores that are already down. However, even those that have already gone off the air can come back at any time, especially around the time of Black Friday. Therefore, it is important to keep an eye out and with the radar turned on.

To facilitate, use the command CTRL+F in the list of non-recommended sites and enter the address of the store you found, to see if it has already received a red alert from Procon.

2. Below market price and unknown stores

It sounds silly to talk, but it’s good to pay attention. If the promotion is priced well below normal, it’s good to be suspicious — either by store error or bad faith. For example, if an iPhone 12 of 64 GB, which has a suggested price of R$ 6,999, is for R$ 4,500, it’s good to double your attention (you can hardly buy for that price even importing from the United States).

When in doubt, it’s worth calling the store’s SAC to confirm the amount and clear up your doubts. If you can’t easily find the company’s contact or CNPJ information, that’s another reason to get a flea behind your ear.

3. Importance of checking store reputation

As important as it is to avoid unfamiliar stores, sometimes you’ve never seen the store before, but it acts in good faith. Or even the well-known stores have high complaint rates and should be avoided for less headaches.

Thus, another very important tip is to check the store’s reputation on sites such as or Just type the name of the establishment in the search field and search. You can see the percentage of requests fulfilled, solution rate, satisfaction, average response time, and various other important information.

4. Reliable shopping recommendations

5. Price comparison

It’s important to realize that a good discount at a store might not mean the product is cheaper than elsewhere. So visit different websites and compare the price of items to see where it’s most worth buying. Also simulate the total value of the product + shipping, sometimes this is the trick.

A site that can help you in this mission is Buscapé. When looking for what you want to buy, the company presents you with a list of offers for the desired product.

6. Conditions for the right of repentance — what to know

According to art. 49 of the Consumer Defense Code (CDC), the consumer has 7 calendar days to regret what he bought over the internet or over the phone, from the date of receipt of the product. The amount paid for the purchase is refunded in full.

However, some stores make return conditions difficult; some specify that the product cannot even be opened, for example. So, check the conditions that are given in the right of repentance to avoid headaches.

7. Be careful when shopping on public networks

It’s a more general tip, but it’s also true for Black Friday: be careful when shopping on public networks, as you need to enter sensitive information in your browser, such as credit card data, and this information can be intercepted by someone with a technical knowledge on the subject.

Always prefer to make the purchase on a private network, protected by a password and from someone whose origin is trustworthy. If you are in a place other than your home, consider using a VPN to protect your data.

8. How to know if the site is secure

It’s no use using a VPN if, on the other side, the site you are browsing or intending to make a purchase is not protected. Especially when there are several leaks from technology companies, fintechs and even telephone operators. Security never hurts.

If even large companies, with professionals dedicated to taking care of infrastructure and security, have breaches and suffer leaks, what can be said about small sites? Unfortunately, in this case the user cannot take any action other than to avoid the store.

Therefore, make sure the site you found a product on is secure, to avoid scams or exposure of your data in the future.
