A start-up based in Sao Paulo's second-largest favela, Paraisopolis, says it will make some eighty-thousand deliveries around the city's favelas during this year’s Black Friday.

This Friday (29), many take advantage of the night to make their purchases. Stores are full of tempting offers, attracting large numbers of consumers. The search for products on sale is great, with everyone wanting to take advantage of the best prices.
