Hack 13 · Stop Wasting Money
"Would I Buy This at Double Price?" Test
This is a one-question filter you apply before any nonessential purchase: if it cost twice as much, would you still buy it? The question cuts through sale pricing and urgency, because it forces you to judge the item on value rather than on the discount. Used consistently, it stops a large share of impulse purchases without requiring any willpower.
How to do it
- Pause before any nonessential purchase and ask the doubling question.
- If the answer is no, walk away rather than negotiating with yourself.
- Check the price history when a deal feels urgent.
What it typically saves
Typically several hundred dollars a year in avoided impulse purchases.
Questions people ask
Why does doubling the price work?
It separates wanting the item from wanting the bargain. A lot of purchases are really a reaction to the discount rather than to the thing itself.
Does this apply to essentials?
No. Use it on discretionary purchases only, or you will end up applying it to groceries and making worse decisions, not better ones.
What if it genuinely is a rare deal?
Price history tools will tell you quickly. Most limited-time offers are neither limited nor unusual once you can see the past year of pricing.
