Yes, you can save 10% to 20% or more on your travel expenses by shopping at large supermarkets (Hypermarkets) such as Homeplus, E-mart, and Lotte Mart instead of convenience stores. While convenience stores like GS25 or CU are open 24/7 and offer the convenience of instant ramen stations, large supermarkets provide significantly lower prices and a wider selection of goods. Importantly, these hypermarkets allow for small, individual purchases—unlike warehouse clubs like Costco or E-mart Traders which require bulk buying.
