This November 26 takes place Black Friday, a date in which many consumers have the opportunity to take advantage of offers, promotions and discounts on different products.
Some businesses have advanced the date on which these celebration begin, in which many people also take the opportunity to advance the purchase of Christmas gifts.
One of the most recurrent practices by some stores or companies is to increase the prices in products before this date, and then lower them with the arrival of this day so awaited by customers. So you can check if a product was cheaper before Black Friday.
To check if the prices were cheaper or more expensive, there is an application that allows us to find out. The ‘CamelCamelCamel‘ app, which is used to check the prices of companies such as Amazon, a very common resource at this time.
