An Unbeatable Scheme

A guide to getting (marginally) rich(er) quick(-ish):
  1. Take one promotion code offering free gambling credit when you deposit a small amount of cash in an online gambling site.
  2. Sign up for said site and deposit money, earning yourself a supermarket voucher of equal value as well as credit to use on the site.
  3. Bet the deposit money and the bonus money, earning at least a fraction (if not a multiple) of the total amount, and almost certainly more than the initial investment.
  4. Do not become addicted to gambling.
  5. Cash out all winnings.
  6. Go out and buy new suits.
