[Broke AF] What is the cheapest thing you've done that you're not really proud of but also kinda proud of?

Mine wasn't really to save money, but it was to make money. Recently Tiger Brokers has a promotion for refererrs. They would give a $60 SGD stock voucher to individuals who referred their friends to open an account with Tiger. So after knowing that, I convinced around 11 of my friends to sign up, paying them $10 each. That left me with a $50 net gain per person, and I made over $500 from that alone, in 2 days.

Recently, I was booking a cab home from a mall. The mall has 3 possible pickup points. Booking the cab from the entrance nearest to me was going to cost me $16.30. After checking the price for the other pickup points, I found that the furthest one (which wasn't really far anyway - a 1min walk away) would only cost $14.30.

That 1 minute of walking saved me $2 and I felt like a boss.
