the last week of november sees black friday sales sign pop up everywhere - the concept of 'black friday' originates from the united states, where every year, on the friday that directly follows thanksgiving thursday - retailers sell their products at highly reduced rates, providing an excellent opportunity for shoppers to make cheap purchases, a particularly shopping opportunity for anyone preparing for christmas.

starting in 2010, busca descontos has brought the concept of black friday to brazilian shoppers - companies make special promotions and deals in conjunction with the website, and black friday then notifies registered customers about the best online deals available to them.

in 2014, a range of new features were introduced to the website, including new product categories and a wide range of articles -  the site also includes prizes such as a trip to new york city, in order to experience the discount haven in its birthplace - the website continues to facilitate a mutually beneficial relationship between retailers and customers. 

a discount that may be found in many stores throughout rio de janeiro is if there is a payment made in cash, called pagamento à  vista - not all venues offer a cash discount, but those that do usually offer a discounted percentage around 5%.  this is also a great way to build great rapport between buyers and sellers.
