Peruvian blogger Cyrano from Columna 17 [es] shares a curious incident he experienced some days ago, when a salesman knocked on his door and offered him [es] a set of five different-sized tupperware for 10 soles (about four dollars) and a bag of any size from a well-known local supermarket:

In Peru, just one medium-sized tupperware may cost between 7 and 10 soles. Here I had five of them for a third of the whole price. Besides that, a bag?! That is costless, once I bring them [the bags] home, they are used to wrap and dispose garbage, previously classified for so-called recycling.
