Jeff Kreisler, Comedian & Author — Spent with Lindsay Goldwert

Tell me if this has happened to you. You see an app or service you want to try. You're on the fence. But it's offering you the first month free. So you take the plunge. It's free, right? And if you don't like it, you can cancel.

Then, you forget to cancel.

And it shows up on your credit card bill for at least two pay cycles before you tell them to stop billing you for it. Or you just keep paying for it. That free trial has just cost you plenty.

Today, I sit down with Jeff Kreisler, an award-winning comedian and author of "Get Rich Cheating" works in the interesting realm of behavioral economics -- why we spend money on things when we shouldn't. Jeff tells us the cost of free and why we'll always end up paying.
