Many online brokers are willing to pay you to start investing with them. It's a competitive world, and they know if you stick around, you will help them earn a lot of money.
Here are a few examples:
Scotttrade is offering up to $2000 cash bonus for signing up with them and depositing a money into your account.
Etrade is offering up to $2500 in cash for signing up with them and depositing a certain amount of money into your account.
Most online trading brokers have promotions to attract new customers and to get customers to switch to them.
If you're not in the investing game, you should be. It's pretty much a necessity if you want to retire comfortably. Most people choose an online broker like the ones I mentioned above to start trading.
