Zecco.com is an online brokerage with an amazing deal: 10 FREE stock trades every month to customers who keep only $2,500 in assets in their account. Stock trades are just $4.50 each otherwise. There’s no annual fee or minimum balance. There's no catch. This is not an introductory offer. Zecco is able to give away free trades because the cost of executing a trade has become very low.

TradeKing is a nationally licensed online broker offering low flat fees ($4.95 per trade plus $.65 per option contract) with no hidden costs or account minimums.
