When to use it
Use it when impulse purchases are undermining your budget.
How to apply it
- Write down the item, its price and the date you wanted it.
- Wait 30 days without buying it.
- Revisit the item at the end of the period.
- Buy it only if you still want it and it fits your budget.
- Move the money you did not spend into savings.
Tip: Shorten the wait for smaller items, but keep some pause in place.
