Money for Nothing

Have you ever gotten free money? I once bought a $300 bike with a credit card, but the purchase never showed up on my statement. Another time I spent $95 at a store, but it showed up as 96 on the statement. When I called to complain, they credited me the entire $96, rather than just the extra 1. (In addition, I’d been reimbursed the entire 95 by the friend I’d made the purchase for). I bought mutual funds once via bank transfer, and though the money was never taken out of the bank, I received statements regularly for a year. The funds then proceeded to grow by more than 25%. (They eventually figured this one out and I had to pay, but it was a no lose situation since the funds had grown substantially).
