The offer sounded tempting, but as one woman found, if you don't read the fine print, it could cost you.

Christine Danderand works part time as a freelance makeup artist, so she's always looking through magzines for the latest trends. She went shopping at the beauty store Ulta to pick up some new makeup. "When I made my purchases, the girl at the counter offered me a little card that said with your purchase you're eligible for two free issues of InStyle magazine."

Christine signed up and got her two free issues. "Last week, my husband called and asked what the charge was on our bank account for the InStyle magazine."

Christine found a charge of $23.88 on their statement. She wondered how could Ulta give her credit card information to the magazine company?

Channel 6 News contacted the manager at the Ulta store. They tell us they do give customers the chance to get two free issues of InStyle, but they also give them this info. The fine print reads, "By signing below, you authorize the transfer for your credit/debit card account information to InStyle."

The magazine offer card says, "Should you decide to continue with the magazine do nothing. Should you decide to cancel by calling the toll free number below, you will receive a prompt, courteous refund for all unmailed issues."

Christine called InStyle to stop the charge. "They said that they would reimburse the money that day. It is still not in our account, so we're still waiting for that.”

When it comes to free magazine offers, the Better Business Bureau says always ask, is the free trial offer tied to a membership? Do you have to call the company to avoid getting more merchandise or fees?

Christine says she will never again sign up for free magazines. "Be careful and don't do it. Nothing's free."

The manager of Ulta says the offer is a good deal for customers. They will end up saving more than 60 percent off the newsstand price by signing it.
