Any somewhat risk-free way to use 25 free trades in a 45 day period?

I want to use these for my new Ameritrade acct if it can be done. I got the acct for the free phone but want to leverage it with the free trades if anyone has a good strategy.

Nothing in equities is risk free.

OK, how about something to buy that will beat money market rates over a 9 month

period that is LOW risk?
