With an ongoing political crisis, Brazilians are more concerned about political matters than ever. They're constantly keeping an eye on any news about the government, taking the conversation online and to social networks.
Finding out that the Correios, a state-owned company, had imposed a 51% increase in shipping, online marketplace Mercado Livre brought light to the issue by launching a protest with the hashtag #StopAbusiveShipping.
Everyone sending a letter or an order was invited to participate. All they had to do was write the hashtag on the box - or on an envelope - and send the parcel through Correios, so they themselves could spread the message around all of Brazil.
With zero investment, the campaign brought millions of Brazilians together to fight for the right to buy online with fair shipping.
