This document describes a peer-to-peer textbook rental service called TeRentoMX that aims to make educational materials more affordable and accessible to students in Mexico. It notes that textbook prices are prohibitively expensive for many students, costing on average $150 per semester while Mexico's minimum wage is only $5 per day. TeRentoMX allows students to rent used textbooks from other students for 70% less than commercial prices, saving students money while generating income from unused books. The document estimates the potential market size and revenue opportunity for TeRentoMX in Guadalajara based on textbook spending among the city's 200,000 college students.
