MADISON, Wis. (WRN) — Now’s probably a good time to check and see if you have some unexpected subscriptions.

Watch out for “free trials” you sign up for online. Lisa Schiller with Better Business Bureau of Wisconsin says you should be wary when a “free” trial requires you to pay anything upfront.

“In almost every case that we hear, the free trials will ask for your credit card number because they need to charge you for shipping and handling or something like that,” said Schiller.

Be sure to read the fine print when you sign up, and mark down when you need to cancel that trial before you have to pay. Also be sure to keep track of any recurring subscriptions you do have, and regularly check your credit card or bank statements for irregularities.
