This tip is especially good for enjoying your stroll down those iconic (but pricey) streets while on traveling. If you struggle with impulse purchases, consider carrying a padlock and (discretely) placing your wallet into your backpack and literally locking it up when you walk down streets that sell overpriced (or simply expensive) items. Yes, you will know the combination and be able to unlock it, but it will force you to commit to saving your money and force you to think through your purchase while you take the extra step of unlocking it.
