"Free" - my ass!

At last some idiotic scheme on the boob tube has aroused my sense of incredulity to speak out. "Use my system to cure your insubordinate brats and if it doesn't work - it's FREE!"
Here's how it works - you buy the $300 plan @ $100 a month (plus $15 shipping and handling [non-refundable] each month) If the plan fails to satisfy you (probably) you can apply for a FULL $300 refund (who knows when it will arrive). So, at the end, you have 3 worthless 50 cent DVDs and they have $45 shipping cost plus whatever interest they have earned on your $300. There's a phrase made famous by P. T. Barnum but it eludes me.
I love marketing.
