Korea's 1+1 Deal Culture: How to Shop Smart at Olive Young and Convenience Stores

Walk into almost any store in Korea and you will see signs reading 1+1 or 2+1 on shelves, refrigerators, and beauty displays. In Korea, these promotions are not occasional events. They are part of everyday retail culture.

For travelers shopping for K-beauty products, understanding how this system works can make a surprisingly large difference in total spending.

1+1 and 2+1 Are Everywhere in Korea

1+1 (IL PLUS IL) means buy one, get one free. 2+1 (I PLUS IL) means buy two, get one free. These promotions appear on everything from sheet masks and toners to sunscreen and lip balm.

The products included in these deals rotate constantly, which is why many Korean shoppers check for promotions before buying everyday items.

Korea's retail market is heavily focused on fast product turnover and competitive pricing, so giving customers more products for the same price has become one of the most common sales strategies across convenience stores and beauty chains.

Olive Young Is the Center of K-Beauty Shopping

OLIVE YOUNG (올리브영) is Korea's largest health and beauty chain and one of the most visited shopping destinations for foreign travelers looking for K-beauty products.

The stores carry thousands of skincare, makeup, and wellness items, and a large portion of the products are usually part of ongoing 1+1 or 2+1 promotions.

Promotion labels are clearly displayed on shelves and product packaging, making the discounts easy to identify even for first-time visitors.

Some larger Olive Young locations in tourist-heavy areas such as Myeongdong, Hongdae, and Seongsu also display real-time bestseller rankings among Korean and foreign shoppers.

In some stores, foreign visitors may also qualify for an immediate VAT refund when spending over a certain amount.

Convenience Stores Also Run Beauty and Everyday Promotions

Korea's major convenience store chains, including CU and GS25, run rotating 1+1 and 2+1 promotions across almost every product category. Drinks, snacks, ice cream, and instant foods are where most visitors first notice the system, but the same deals apply to beauty and skincare as well.

The beauty selection is smaller than Olive Young, but the stores are easy to find and often stock travel-sized cleansers, sheet masks, sunscreen sticks, toners, and other daily essentials.

Some 7-Eleven Korea concept stores have also introduced dedicated K-beauty sections with similar promotional systems.

In some cases, products sold through convenience store promotions can end up cheaper than comparable items at larger beauty stores.

The Virtual Fridge: How Koreans Save Their Free Items

One feature many foreign visitors miss is Korea's "virtual fridge" system.

If you buy a 1+1 product at CU or GS25 but do not want to carry the extra item immediately, you can digitally store the bonus product in the store's app.

To use this feature, you need to download the app first. CU uses the Pocket CU app, while GS25 uses the Our Neighborhood GS app. Both are available for download on foreign app store accounts as well as Korean ones.

Once the app is installed, tell the cashier at checkout that you want KEEPING (키핑). The free item is then saved to your app and can be collected at any branch of the same chain before your trip ends.

This system is commonly used by Korean customers and is especially useful for travelers who do not want to carry extra drinks, snacks, or skincare products while moving around the city.

Timing Matters if You Want Bigger Discounts

Olive Young runs a monthly promotional event called OLIVEYOUNG DAY (올영데이), usually held around the 25th to 27th of each month.

During this period, existing 1+1 promotions are often combined with app coupons and additional discounts.

Olive Young also holds larger seasonal sale events four times a year, typically in March, June, September, and December.

During these sales, the number of 1+1 and 2+1 products increases significantly, making them some of the busiest shopping periods of the year.

Convenience store promotions do not follow the same fixed schedule, but new deals are commonly updated at the beginning of each week.
