Hi Angel, I have encountered a somewhat similar system in some supermarkets in Germany. It does not only work with fruits and vegetables, but also with any other kind of product that is about to hit it's expiration date. I always like to check out those boxes, both out of principle and because it is nice for a student budget. One problem with these existing solutions, in my opinion, is the display. They are usually stuffed into a box or a shopping cart in some corner of the market and you have to actively search for them. I think a better way to market & display odd or soon-to-expire products could definitely have an impact. Love your idea!
