In relation to the guidelines produced by the team from Techblog, the denunciation of some users about Casas Bahia’s Black Friday generated debate on social networks. For a few moments last Friday (26), the Samsung Galaxy Note 20 and Galaxy S20 FE were on sale for R$ 679 and for around R$ 1 thousand, respectively.

As this value is well below the value normally practiced, between R$ 2,500 and R$ 3 thousand, several users tried to buy the products. However, without success. The store ended up canceling the orders and the case ended up at Procon. To better understand the case, just access the article published on the 29th.

Later, the retail chain ended up informing that it would only honor purchases of the Galaxy S20 FE. Via, the company responsible for the brands Casas Bahia, Ponto and, said in a statement that the price variations of Galaxy Note 20 smartphones were due to a processing failure.

Finally, running away from the Black theme Fraud Friday, a bill aimed at banning the use of Pix in São Paulo also caught the attention of readers.

Bill 583/21 by state deputy Campos Machado (Avante), of São Paulo, seeks to prohibit all financial institutions in the State of São Paulo from offering Pix to users. At least, until the Central Bank (BC) demonstrates in a technical report which security mechanisms are created to prevent fraudulent transactions or those made by criminals through theft or kidnapping.
