You should sign up and get an account at RobinHood. This is a no fee brokerage firm that gives members a free stock when they join. The referrer also gets a free stock as well. Naturally, this only works in the USA, but I find it's great for me and allows me to buy stocks one at a time to build up my portfolio.
Join Robinhood and we'll both get a stock like Apple, Ford, or Sprint for free. Make sure you use my link.
