The supermarket told CNBC that the "ugly" products available on each of their one-off operation were all sold, but were unable to provide any specific sale figures.
Since then, the supermarket chain has repeated the one-off operation in a dozen of its Parisian stores and other French retailers were quick to follow in the chain's footsteps.
According to the Food & Agriculture Organization (FAO) of the United Nations, 30 percent of global food production is lost after harvest, or wasted in shops, households or catering services, representing $750 billion worth of food every year – and a lot of this food is just thrown away before it hits the shelves because it doesn't conform with the idea of what a piece of fruit or vegetable should look like.
Furthermore, the organization highlights that in industrialized countries, 40 percent of food losses occur at the retail and consumer level and, estimated at around 222 million tons, this represents just about the total net food production in Sub-Saharan Africa.
"I'm very happy with this initiative", Robert van Otterdijk, agro-industry officer at the FAO told CNBC.
"The idea and willingness of retailers to go this way are extremely positive."

A missed opportunity
The French initiative is not isolated. Other supermarkets have started to relax some of their standards. Sainsbury's, the U.K.'s third-largest food retailer by market share, is one of them. Although the vegetables they sell is not defined as "wonky", the retailer started selling smaller or irregular shaped fresh produce in its "Basic" after a drought impacted British crops in 2012.
But for Martin Bowman, U.K. gleaning coordinator at the Feeding the 5k campaign – which focuses on tackling food waste at the global scale - British supermarkets do not do enough to promote misshapen produce.
