How to Actually Save Money on a Trip to Korea

Exchange money at a private money changer in downtown areas (like Myeongdong's exchange alley) rather than the airport — rates are noticeably better. Travel debit cards like Travel Wallet or Travelog charge no exchange fee and use the real-time rate.
A rechargeable T-money card is far cheaper than single tickets — transfer discounts apply automatically, so switching between subway and bus rarely adds extra fare.
Late at night, skip the taxi and take an Owl Bus (N-bus) instead — much cheaper, running key Seoul routes from midnight to 5am.
Buy tickets for major attractions in advance through foreigner-focused platforms like Klook or Trazy — often cheaper than paying at the gate.
Convenience-store rice balls and lunch boxes can cover a meal for around 5,000 won, which adds up to real savings over eating at restaurants every meal.
Traditional markets (Gwangjang Market, Namdaemun Market) are noticeably cheaper than tourist-area restaurants while still delivering authentic local flavor.
Free Wi-Fi is widely available on the subway, in cafés, and at convenience stores — instead of a pricey data plan, a short-term eSIM used only when needed can be enough.
