I was just about to do it, too.
I’m talking about buying something on sale. Don’t get me wrong — I love a bargain. But buying on sale is tricky. It’s easy to fall into “but it was on sale” rationalization.
There’s only one question to ask yourself when you’re about to grab that shirt that’s 30% off. Would you have purchased it when it was full price?
If “yes” it’s a true score. Otherwise…well, you know what to do.
