A shopper prepares to pay at an informal shop piloted by Pick n Pay in Soweto, South Africa February 25, 2016. Pick n Pay, a grocer focused on the middle and upper end of the market, on Thursday piloted a project to supply informal shops, called "spazas". The trial could be extended to hundreds of independent spaza owners if successful, it said. REUTERS/Siphiwe Sibeko
