Condoms. I was 11 and we were just hitting puberty when I decided to walk into a pharmacy at a whim and buy condoms. My lunch money at the time was 30 PKR (.30 USD) a day. And a quick trip to the pharmacy and an awkward conversation with a guy there told me a 3 pack of cheapest condoms was 5 PKR (0.05 USD) Long story short, I sold condoms at 15 PKR a piece, made a profit of 40 PKR (20x cost). No one else was brave enough to buy a pack at the pharmacy so I enjoyed my position for the next two years.
