So you walk by a store window and there it is: the one product you need—and at half price! Great, right? But if you take the time to think about it rationally, you might realise that you just want it—but you don’t actually need it. It won’t solve any problems, and all it will help you do is save less money.
But faced with the deal, the temptation is quite intense. If you go into the store and pick up that item, you might end up buying something that you don’t need. Here’s where the 72-hour trick comes into play.
The rule says: Once you happen upon one of those incredible deals that you just can’t pass up, wait at least 72 hours (three days) before buying it. For this to have the desired effect, put a note in your wallet with the name of the item or service as well as the price. Many times less than two days will go by before you get rid of the note, realising (rationally) that you don’t need it.
