many of these feiras happen over the weekend, around 37 percent - wednesday comes in second as most popular, with about 15 percent, then thursday, with approximately 13 percent. 

while the 1970s saw a grand shift in the feira's importance, as supermarkets gained prominence over the street market, some believe that the feira is beginning to recuperate its original fame - while these may only be theories, there is certainly clear increase in the volume and arrival of new products and services at the feiras.

one major difference between the local supermarket and the feira are prices - most often the supermarket has cheaper fresh goods because of their negotiating power, however, many argue that the feira have high quality of foods on sale, hand-picked by the vendor.
