OLX.pt is the most popular online platform of 2nd hand items in Portugal. The category of "school books" has the highest number of results and considering that, the purchase of school materials is a heavy burden for families in Portugal OLX was explored by his range of results of different school materials by searching for keywords that are related to education and school.
