So a couple weeks ago MLB.tv was running a 5-day free trial.  It was the typical, use your credit card to sign up, and you have 5 days to cancel otherwise you get charged for the remainder of the season.

My brother-in-law and I both signed up for the service, and called the morning of the 5th day and cancelled, being assured by the phone reps that we wouldn't be charged.  Well, today we both looked at our credit card bills and they charged us $29.95.

So to anyone who used the trial and cancelled:  check your bill!!
