I used to keep my old textbooks, notes, and handouts stacked in a dusty corner—thinking I might need them “someday.” But eventually, I realized they were just taking up space. So I listed them online—and turns out, junior students were more than happy to buy them. Not only did I earn a little extra cash, I also helped others save money.
Why It Works
New students often look for affordable ways to prepare for upcoming semesters. They’re likely to trust and appreciate notes or books that have already helped someone pass the same classes. Plus, your materials are already organized, highlighted, and annotated—something no new book offers.
Where to Sell

- WhatsApp groups or Telegram channels of your department or faculty
- Instagram stories or dedicated study accounts
- Facebook groups for university or school students
- Online marketplaces like Tokopedia, Shopee, or Carousell
Make sure to include:
- Clear photos
- Short descriptions (subject, condition, highlights)
- Prices that are lower than new copies
Smart Selling Tip
Bundle your items by semester or subject—for example, “Semester 3 Forestry Starter Pack.” It’s more appealing to busy students who just want everything in one go. Bonus: if you scored well in the class, add a note like “These helped me get an A in Forest Policy”—it builds trust instantly.
There’s no need to let your study materials collect dust. With just your phone and a bit of effort, you can turn those notes into something valuable again. What was once clutter becomes cash—and someone else’s academic advantage.
