We know that you’re out looking for a good deal but there’s one trap you don’t want to fall into this holiday season (or any other season for that matter). Those offers for free products in Facebook ads may seem like a steal but if you sign up for them, the only thing getting stolen is your personal information.

These ads appear as sponsored content on Facebook. They promise to send you a free product which can be a knife, pen set, or any other of a thousand things. Now, you will actually receive the product but there are three things that will make you want to avoid following these links.

One, the product will be shoddy. The pictures may look nice but the product (when you eventually get it) will be cheap, mass produced junk. Two, shipping is not free and can be as low as $8 but as high as $30. And three, the biggest reason to stay away: They will sell your information to third parties. Soon after hitting ‘submit’, you’ll be hit with a legion of spam.

Next time you see one, hit hide or better yet, report them.
