I continue to marvel at how people in advertising have no idea how percentages work. When a company advertises that they can save you “up to 80%” but then show an example of a customer who owed $977,100, but paid the IRS just $1000 (let’s be clear, the savings was just under 99.9% here), you know we have an issue.

By the way, if anyone is reading (?) I’d love you to send an example of your own. Leave a comment, and I’ll get right back to you.)
